How to Use CBD Oil for Chronic Spinal Stenosis Pain

Cannabidiol (CBD) is rapidly growing in popularity as an excellent therapeutic compound thanks to the numerous positive studies and legislation that approve its use for an increasing number of medical conditions. A lot of people these days are looking towards cannabis wiki stores to buy the product.

While this herb can help treat minor complaints such as nausea, insomnia, and migraines, more and more people are using CBD oil to relieve aches and pains from long-term spinal diseases such as spinal stenosis. In recent studies, cannabidiol has shown to be safe with very few side effects experienced by patients.

What Exactly is Spinal Stenosis?

Spinal stenosis refers to a condition when the spinal column narrows and begins to compress the spinal cord. If the narrowing is only minimal, there are no symptoms that occur but excessive narrowing can compress the nerves, causing problems.

The spine is made up of a series of bones called vertebrae, which provide support and stability for the upper body. Spinal nerves travel through the openings of the vertebrae and send signals from the brain and to the rest of the body.

The leading cause of spinal stenosis is aging. As we age, the degenerative process happens throughout the body. Spinal tissues may begin to thicken, while the bones may get bigger, causing pressure to the nerves. Rheumatoid arthritis and osteoarthritis can be contributing factors to spinal stenosis because the inflammation they cause can place pressure on the spinal cord.

Other possible causes of spinal stenosis include:

  • An accident may injure a part of the spine, leading to inflammation
  • Herniated discs. Material may seep out when cushions are cracked, putting pressure on the spinal nerves.
  • Cancerous growth that touches the spinal cord may compress the nerves
  • Paget’s disease. In this condition, the bones grow unusually large. This narrows the spinal canal, causing nerve problems.

Spinal stenosis often affects the lower back or neck, but not everyone exhibits symptoms. If you do, they tend to be similar – numbness, stiffness and back pain.

CBD Oil for Chronic Spinal Stenosis Pain

Endocannabinoids – cannabinoids produced by the body, work as tiny circuit breakers of the nerve endings. Experts have found that these cannabinoids, whether plant-derived or produced by the body, serve as inhibitors or circuit breakers of pain pathways, and thus, play a major role as an analgesic and even as an anti-inflammatory agent.

CBD oil, which contains a high amount of cannabidiol, a form of cannabinoid, has been used for treating many conditions associated with neuropathic and inflammatory causes. Conditions such as spinal stenosis arise due to a pre-existing inflammatory reaction, which can be alleviated using CBD oil.

How to Use CBD Oil for Spinal Stenosis Pain

One of the most common symptoms associated with spinal stenosis is back pain. CBD topicals tend to work well to alleviate and relieve the pain by directly targeting the specific inflamed area.

CBD Oil. Spinal stenosis, which arises due to previous or ongoing inflammatory reaction may be improved using CBD oil. It can help reduce inflammation, provide symptom relief of nerve-related conditions such as neuropathy and help reduce motor and sensory weakness and the tingling sensations of spinal stenosis.

“Besides treating inflammatory conditions, CBD oil can also help manage anxiety and insomnia, which are some of the discomforts associated with spinal stenosis.”, says Pure Path CBD Oil.

CBD Lotion. The application of CBD lotion directly to the area offers topical relief. Lotions and balms containing cannabinoids are quickly absorbed and bind to pain receptors.

Other methods you can use include CBD edibles and ointments.

Conclusion

The current therapeutic management for spinal stenosis includes pain management using pain medications and physical therapy. CBD oil has been proven as a potential treatment for spinal stenosis pain because it can alleviate symptoms and can help reduce inflammation.

“Consult your doctor before using CBD oil for chronic spinal stenosis pain.”, says CBDWorld.

Cannabinoids and spinal cord stimulation for the treatment of failed back surgery syndrome refractory pain

This study aimed to evaluate pain and its symptoms in patients with failed back surgery syndrome (FBSS) refractory to other therapies, treated with a combination of delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), in association with spinal cord stimulation (SCS).

Settings

Outpatients referred at Pain Unit of San Vincenzo Hospital in Taormina (Italy), between September 2014 and January 2016.

Subjects

Eleven FBSS patients diagnosed with neuropathic pain using the Douleur Neuropathique 4 questionnaire and suffering from moderate to severe chronic refractory pain, and undergoing treatment with SCS and a combination of THC/CBD for 12 consecutive months.

Materials and methods

All the included patients discontinued previous unsuccessful therapy at least 2 months before the beginning of the cannabinoid therapy, with the exception of the SCS that was continued. Patients received a fixed dosage of cannabinoid agonists (THC/CBD) that could be increased subjective to pain control response. A Brief Pain Inventory questionnaire was administered to measure pain and its interference with characteristic dimensions of feelings and functions. The duration of treatment with SCS and THC/CBD combination was 12 months.

Results

Effective pain management as compared to baseline result was achieved in all the cases studied. The positive effect of cannabinoid agonists on refractory pain was maintained during the entire duration of treatment with minimal dosage titration. Pain perception, evaluated through numeric rating scale, decreased from a baseline mean value of 8.18±1.07–4.72±0.9 by the end of the study duration (12 months) (P<0.001).

Conclusion

The results indicate that cannabinoid agonists (THC/CBD) can have remarkable analgesic capabilities, as adjuvant of SCS, for the treatment of chronic refractory pain of FBSS patients.

Introduction

Failed back surgery syndrome (FBSS) is defined by the International Association for the Study of Pain as “a spinal pain of unknown origin either persisting despite surgical intervention or appearing after surgical intervention for spinal pain originally in the same topographical location”. 1 Several conditions have been identified as underlying causes for FBSS, such as epidural fibrosis, global or lateral canal stenosis, foraminal stenosis, retained disc fragment, recurrent disc herniation or degeneration, spinal instability, facet joint pain, sacroiliac joint pain, discitis, adhesive arachnoiditis, and others. 2 The percentage of the insurgency of chronic pain after spinal surgery varies significantly ranging from 5% to 74.6%, and the percentage of the need for re-operation is between 13.4% and 35%. 3 Up to 20%–40% of patients who have undergone lumbar spine surgery experience FBSS. 4 Nowadays, this syndrome affectŝ0.02%–2% of the general population. 5 The FBSS patients frequently suffer from moderate to severe chronic pain, associated with sensory and/or motor deficits, as well as other severe chronic pain syndromes associated with the persistence of low back pain, deterioration or recurrence of radiculopathy, and sphincter dysfunction. 6 , 7 The current therapeutic strategies for FBSS include antidepressant medications, antiepileptic medications, 8 deep brain stimulation, spinal cord stimulation (SCS), 9 , 10 epidural and intrathecal injections, 11 , 12 spine surgery, 13 counseling, 14 and exercise therapy. 15 FBSS is considered an intractable syndrome when various combinations of the existing therapeutic strategies prove ineffective. Opioids and their major adjuvants usually produce positive results in the treatment of chronic pain, especially when other therapeutic approaches fail. There is an increasing demand for alternative therapeutic strategies by patients and clinicians when available therapies are marginally effective, or not well tolerated. In this context, the authors assessed the effectiveness of an alternative approach for chronic refractory pain associated with FBSS, using cannabinoids as a multimodal treatment approach to neuropathic pain. The plant Cannabis sativa L. has been used for centuries, both for recreational and medicinal purposes. Only in recent times, studies about exogenous cannabinoids have been performed to evaluate their therapeutic value and to investigate the role of endogenous cannabinoids (endocannabinoids) in physiology and pathophysiology of many neurologic and neuropsychiatric diseases. 16 – 18 Several types of insults which can damage the peripheral or central somatosensory nervous system, including FBSS, can cause neuropathic pain. It is estimated that 7%–8% of the population in developed nations is suffering from neuropathic pain. 19 To date, therapeutic options for neuropathic pain induced by FBSS achieve effective analgesia in only less than 50% of the cases. 20 This pain could, however, be effectively treated by drugs modulating endocannabinoid system. 21 This system is highly expressed in neurons and immune cells, and it plays a crucial role in the development of neuropathic pain. 22 This pilot study aimed to evaluate the effect of a combination of delta-9-tetrahydrocannabinol (THC)/cannabidiol (CBD) in FBSS refractory to other available therapeutic strategies, including opioids, adjuvant drugs, radio frequency neuromodulating treatments, and SCS alone. The SCS, a treatment modality for chronic pain that has been in use since 1967, 9 is an expensive therapy and careful selection for its suitability is recommended. Remarkable technological advances over the years have resulted in electrodes transitioning from single to multi-contact arrays and stimulators from external radiofrequency coupled to implantable rechargeable devices. Current implantable SCS electrodes can be inserted percutaneously through a Tuohy needle using essentially the same technique as that used for an epidural catheter. 23 In this context, a retrospective study documenting the results obtained with oral administration of cannabinoids agonists, namely a combination of THC/CBD, in eleven refractory FBSS patients is presented.

Materials and methods

This article reports a retrospective study, performed at Pain Therapy Unit of San Vincenzo Hospital of Taormina, in collaboration with the Anesthesiology and Pain Therapy Unit and the Department of Biomedical and Dental Sciences and Morphofunctional Imaging of the University Hospital “G. Martino” of Messina. All outpatients included in the study were referred at the Pain Unit of San Vincenzo Hospital, during the period between September 2014 and January 2016. Treatments were performed in accordance with rules and ethical standards on human experimentation and the Declaration of Helsinki of 1964 (further revised in 2013). All the study participants gave written informed consent (including information on possible risks and side effects) for participation in the research study. Every precaution was taken to protect the privacy of patients. The retrospective study was approved by the Local Ethics Committee (Comitato Etico Interaziendale della Provincia di Messina) with protocol number 61/17, and the clinical study is registered with the number <"type":"clinical-trial","attrs":<"text":"NCT03210766","term_id":"NCT03210766">> NCT03210766 (www.clinicaltrials.org). Between November 2014 and December 2015, authors included the clinical records of eleven FBSS patients suffering from moderate to severe chronic pain not responsive to other treatment regimens (including neuromodulating techniques), and considered eligible according to the inclusion and exclusion criteria established for the study. The patients, aged between 49 and 77 years (median age 61.18±10.26 years), were equally distributed (six males and five females) ( Table 1 ). Primary inclusion criteria in this study were the diagnosis of FBSS refractory to other standard treatments. Patients who had not discontinued their previous oral analgesic therapy, at least 2 months before the beginning of the treatment with cannabinoid agonists, were excluded. The SCS therapy, unsatisfactory in terms of pain perception as observed from baseline numeric rating scale (NRS) values, was not discontinued ( Table 1 ). Cannabinoid agonists (THC/CBD) were administered in association with SCS for a treatment period of 12 consecutive months.

The neuropathic pain was assessed using the Douleur Neuropathique 4 (DN4) questionnaire in all the cases studied. The DN4 questionnaire consists of a total of ten items, of which seven items are related to the characteristics of pain (burning, painful cold, electric shocks) and its association with abnormal sensations (tingling, pins and needles, numbness, itching), and three items are related to neurological examination in the painful area (touch hyperesthesia, pinprick hyperesthesia, tactile allodynia). The value of 1 was given to each positive item, and 0 value to each negative item. The total score was calculated as the sum of all ten items and the cutoff value for the diagnosis of neuropathic pain was established as a total score of 4/10. 24 Basal DN4 scores of patients ranged from 7/10 to 10/10 (mean =8.9±1.37). The Brief Pain Inventory (BPI) allows patients to rate and refer the severity of their pain and the degree by which pain interferes with common dimensions of feelings and functions. The BPI was performed by all the patients both at the first visit and at the end of treatment (after 12 months). Initially developed to assess pain related to cancer, the BPI has shown to be an appropriate measure of pain caused by a wide range of clinical conditions. The BPI is a eleven-item questionnaire that consists of four 0–10 NRS items asking patients to rate their pain at its “worst in the last 24 hours”, “least in the last 24 hours”, “average”, and “actually”, with 0 indicating “no pain” and 10 representing “pain as bad as you could imagine”. The remaining seven BPI items probe the degree to which pain interferes with general activity, mood, walking ability, normal work, relations with other people, sleep, and enjoyment of life, again using a 0–10 value scale. For these interference items, 0 (zero) represents “does not interfere” and 10 indicates “interferes completely”. 25 Baseline NRS scores for average pain at visit ranged from 7 to 10 (mean =8.15±0.98) ( Table 1 ). Patients were visited weekly in the first month and every 2 weeks for the entire study duration. All patients received an oleic suspension of THC (19%) and CBD (<1%), 25 mg/day for oral administration. The dosage of cannabinoid agonists could be increased, depending on the positive response to pain control.

Statistical analysis

The numerical data were expressed as the mean ± standard deviation (SD). For each numerical parameter for basal observation and after treatment, we separately performed statistical comparison using the Mann–Whitney test. For each numerical parameter, considered separately for basal and final values, we performed a comparison between basal observation and after treatment to evaluate the existence of a statistically significant difference using the Wilcoxon test.

Results

In FBSS patients treated with the THC/CBD combination, an analgesic effect was achieved in four cases within the first month of treatment. The effect of cannabinoid agonists on refractory pain was maintained during the entire observation time with minimal dosage titration. The mean pain perception calculated using the NRS decreased from 8.18±1.07 at first visit to 4.72±0.9 at the end of the observational time in all cases ( Table 2 ), thus indicating marked analgesia with the treatment. The THC/CBD combination significantly reduced burning sensation and paresthesia linked to FBSS. The BPI interference examination showed that all the patients reported improvement in the quality of sleep (11/11; P<0.01). Additionally, THC/CBD combination enhanced mood as indicated by the rise in baseline mean level of 5.54±0.52–3.63±0.5 by the end of the study period (P<0.001). Remarkably, similar results were obtained with every item on the questionnaire.

Discussion

FBSS is a symptomatological syndrome, influenced by physical, psychological, and psychosocial factors that contribute to worsening individual quality of life. The pathological mechanism of intractable pain related to FBSS is complex and includes permanent inflammatory, neuropathic, and compressive processes, and in some cases are not susceptible to medical or surgical resolution. 26 Treatment for this category of patients aims to achieve relief from pain and consequently improve quality of life and daily activities. The diagnosis of FBSS through clinical history or history of spine operation is not always easy. Physicians should find the underlying causes of the pain and the mechanisms responsible for its maintenance and enforcement. Only an accurate diagnosis can potentially lead to the implementation of appropriate pain management strategies; this is particularly true for neuropathic pain (of radicular, ganglion, or spine origin) which is initiated by nervous system lesions or dysfunction and can be maintained by several different mechanisms. Moreover, neuropathic pain is more likely to be caused either by surgical treatment or associated diseases (comorbidity) and is more difficult to treat than nociceptive pain. 4 Successful treatment outcomes are difficult to achieve for chronic pain which can, in the long run, adversely affect the patient, health care services, and eventually the society. Although SCS can successfully induce analgesia initially, this has been observed to be relatively temporary, with the analgesia usually wearing out after 12–24 months, 9 as in the presented study. In this scenario, the quick onset and prolonged analgesic effects obtained with cannabis-derived products seem to be independent of the effect of prior SCS therapy. From the results obtained, the superior analgesia combined with the low incidence of adverse events suggests that cannabis-derived products may be a valuable therapeutic option for chronic refractory pain associated with FBSS, in comparison to other drug classes including opioids. Cannabis-derived products have been used historically for chronic pain, and are attracting renewed pharmaceutical interest for analgesia. Epidemiological studies show that 10%–15% of patients suffering from chronic pain use cannabis to improve pain, sleep, and mood. 18 Cannabinoid compounds mediate their pharmacological actions by binding to the cannabinoid receptors, namely cannabinoid type 1 receptor CB1 and cannabinoid type 2 receptor CB2. The CB1 receptors are located predominantly in the nervous system, while CB2 receptors are present in the immune cells. 17 Moreover, several authors have described cannabinoid neurophysiological system as distinct but functionally similar to the opioid pain modulation system. 27 Recent clinical trials, investigating the effects of the newest formulations of synthetic and naturally derived cannabinoids, demonstrated their analgesic properties for refractory neurogenic pain, brachial plexus injuries, and chronic neuropathic pain. 16 These studies suggest that the administration of cannabinoid agonists should be considered in patients suffering from chronic moderate to severe pain, especially when other less invasive treatments and opioid therapies fail, or when extreme adverse events are reported. 28 The plant genus Cannabis contains a complex mixture of phytochemicals (over 60 compounds) known as cannabinoids. Among the cannabinoids, the most investigated are the two major active chemical constituents, namely THC and CBD. Cannabinoids are mixed polyketides derived biosynthetically from malonyl-CoA and hexanoyl-CoA units prenylated with geranyl phosphate. 29 THC is the main psychoactive type of cannabinoid, whereas CBD is the major component of cannabis with a distinct pharmacological and psychotropic profile to THC. CBD (C21H30O2) is a resorcinol-based compound devoid of the psychoactive effects of THC and, on the contrary, is believed to be able to attenuate the psychotomimetic effects induced by high dosages of THC. Selective CB2 agonists may reduce central effects, but these are not clinically available. The mechanism of action of CBD is complex and not fully known since this molecule is a “multifaceted-target” drug interacting with several non-endocannabinoid systems such as receptors, ion channels, enzymes, and transporters. 30 CBD modulates the activity of many cellular effectors, including the receptors CB1 and CB2, 31 GPR55, 32 5HT1A, 33 μ- and δ-opioid, 34 peroxisome proliferator-activated receptor gamma (PPARγ), 35 the transient receptor potential subfamily V member 1 (TRPV1) cation channels, 36 and fatty acid amide hydrolase (FAAH). 37

In Italy and other European countries, only a single product consisting of a THC/CBD oromucosal spray has been authorized by the regulatory agency for the treatment of multiple sclerosis spasticity. However, other cannabis flower preparations may be prescribed for patients suffering from chronic pain conditions, refractory to conventional therapy. In the present study, orally administered oleic suspension of THC (19%) and CBD (<1%) was chosen chiefly because the pharmacokinetic data indicate that intake of “high content” of THC cannabis oil results in detectable plasma concentrations of THC as compared to ingestion of “low content” of THC cannabis oil or “mid-content” THC oil-containing capsules. 38 Additionally, the availability of the product and the simplicity offered by the oral route of administration for the oil suspension, in comparison to vaporization, were favorable factors in choosing this formulation. Due to the lack of precise information on efficacy and safety of the product, the study protocol involved an initial low dosage to be increased according to the patient response.

In the cases described in the present study, the analysis of results confirms the positive effects of treatment with THC/CBD in patients with refractory FBSS pain. Moreover, results from BPI examination show an improvement in mood and general activities as well (P<0.001). Overall, THC/CBD combination was well tolerated and not associated with any severe side effects. However, the small number of cases and the lack of a control group are limiting factors for this study to assess a definitive effect and/or for the identification of patient population for which treatment with THC/CBD may be appropriate. The positive effect of THC on the quality of sleep, reported in our study, has already been observed by other authors, 39 and could perhaps positively influence pain perception. To the best of our knowledge, this is the first study reporting the beneficial effects of a combination of THC/CBD in FBSS refractory pain. Preliminary studies on cannabis and sleep suggest that CBD may have therapeutic effects on insomnia. Similar effects favoring sleep were observed with THC; however, contradictory findings revealed that this compound decreases sleep latency and could impair sleep quality in the long term. 40 As a consequence, in our opinion, the effects of THC on pain may be independent of an effect on sleep. Finally, cannabis-derived products should be used cautiously in patients with a history of, or current anxiety or panic disorder, as well as for those with potential for reported dependence or abuse. Additionally, careful monitoring is advised for patients with depression and other psychiatric disorders. 41

Conclusion

This is the first study that underlines the beneficial effects of cannabinoids for the treatment of FBSS. The results suggest that THC/CBD combination may represent an innovative and valid strategy to treat disabling symptoms represented by pain, nausea, and sleep disorders in FBSS patients. Furthermore, in these patients, cannabinoid treatment could positively contribute to an improved quality of life. Though cannabinoids can have common side effects such as dry mouth and drowsiness, the side effects profile of THC/CBD combination seems to be milder and well tolerated. The chief limiting factors of this study are the small number of cases of FBSS patients with intractable refractory pain and the lack of a control group, even though it is a general opinion that interpretation of results obtained with placebo-controlled trials may encounter difficulties because of the psychoactive effects of cannabis. Additionally, it must be noted that ethical rules in Italy are very restrictive, especially in the context of pain treatment.

Albeit the limitations, in all the cases reported, the beneficial effect obtained with cannabinoids in association with SCS demonstrate that SCS therapy alone may be not sufficient to provide adequate analgesia.

Finally, we believe that prospective clinical studies are required to assess the real safety and efficacy of THC/CBD combination for chronic FBSS refractory pain. In conclusion, the current study suggest that THC/CBD combination represents an alternative treatment strategy in FBSS patients with chronic and severe pain, refractory to neuromodulating techniques, and is a valuable adjuvant to SCS.
