Can medical cannabis help meralgia paraesthetica?

There is no study of cannabis-based medicines in meralgia paraesthetica, and there is unlikely ever to be one. What exists is the wider neuropathic pain evidence, and a condition that often resolves without any of this.

What meralgia paraesthetica is

Compression of the lateral femoral cutaneous nerve, usually where it passes near the front of the hip. It produces burning, tingling, numbness or sensitivity over the outer thigh, on one side, in a patch with fairly clear edges. It is a sensory nerve, so it does not cause weakness.

It is also spelled meralgia paresthetica, and both spellings refer to the same condition. Common contributors are anything that presses on the nerve: tight waistbands and belts, heavy tool belts, body armour, obesity, pregnancy, abdominal surgery, and sometimes diabetes affecting the nerve directly.

The reason that list matters is that removing the cause is frequently the treatment. A condition that resolves when a belt is loosened does not need an unlicensed medicine.

What the evidence says

Nothing directly. No randomised trial, and no observational series, has examined a cannabis-based medicine in meralgia paraesthetica. Anyone who tells you otherwise is describing the general neuropathic pain literature.

That general literature is worth knowing about, and worth not overstating. The Cochrane review of cannabis-based medicines for chronic neuropathic pain found that they may increase the number of people achieving substantial pain relief compared with placebo, while also increasing withdrawals due to adverse events, and rated the evidence low to very low quality.

Applying that to a specific compression neuropathy that usually resolves is a further step again, and it is a step the evidence does not take for you.

The fuller picture is in medical cannabis for neuropathic pain.

What is normally tried first

Conservative measures, because they work often enough to be the sensible starting point, and because they address the cause rather than the sensation.

• Removing the source of compression, including clothing, belts and equipment
• Weight loss where that is a contributing factor
• Time, since many cases settle over weeks to months
• Where symptoms persist, the medicines NICE recommends for neuropathic pain — amitriptyline, duloxetine, gabapentin or pregabalin
• Local injection or, rarely, surgical decompression, in persistent cases

A specialist considering an unlicensed medicine will expect that ground to have been covered, and the convention that two standard treatments have been tried applies here as everywhere else.

The general requirements — age, a documented diagnosis, the convention that two standard treatments have been tried, and access to your medical records — are covered in What are the requirements?

An honest assessment

This is a condition where a careful specialist may well say no, and where saying no is the right answer more often than not.

The combination of no condition-specific evidence, low-quality evidence in the wider category, and a natural history that frequently resolves without treatment makes this a weak case for an unlicensed medicine. Where meralgia paraesthetica sits alongside a broader chronic neuropathic pain problem, the assessment is really about that broader problem.

If a clinic tells you it treats meralgia paraesthetica with cannabis, ask what evidence that is based on. There is not any.

How a cannabis-based medicine is thought to work in nerve pain

The body has an endocannabinoid system — a network of signalling molecules and receptors running through the nervous system that helps regulate how pain is registered and passed on. Cannabis-based medicines contain compounds that interact with this system, and in neuropathic pain the general idea is that they may temper faulty or exaggerated nerve signalling.

The important qualifier for meralgia paraesthetica is that this mechanism, even if it worked, would only mask the sensation. It does nothing about the physical compression of the lateral femoral cutaneous nerve that is causing the problem, which is why relieving the pressure is the more logical treatment. The two main compounds are thought to act differently, one intoxicating and more associated with pain and sleep effects, the other not intoxicating; the general biology is explained in the endocannabinoid system explained and THC and CBD explained.

What a trial would involve, if it happened at all

In the uncommon event that a specialist judged a trial reasonable — usually only where meralgia paraesthetica sits within a broader, persistent neuropathic pain problem — it would follow the same cautious pattern as any other unlicensed cannabis-based medicine. Treatment starts at a low dose and is increased slowly under supervision.

The usual formats are oils or capsules taken by mouth, which act more slowly and last longer, and dried flower for vaporising, which acts faster but fades sooner; neither is smoked. How each is used is covered in how cannabis-based medicines are taken, and how a starting point is chosen and adjusted is set out in how a dose is decided and adjusted. Given the lack of condition-specific evidence and the tendency of this condition to settle, any such trial would be time-limited, with a clear plan to stop if it did not obviously help.

A follow-up review would weigh any benefit against side effects such as drowsiness and impaired concentration, and against the practical costs of taking a controlled medicine, including the implications for driving. For most people with this condition, that balance does not favour treatment.

Questions worth asking your specialist

Because this is a condition where the honest answer is often no, the most useful questions are the ones that test whether an unlicensed medicine is proportionate at all.

• Has the cause of the compression been identified and addressed?
• Have the standard neuropathic-pain treatments and conservative measures been tried?
• Given there is no evidence in this specific condition, what is the case for a trial in me?
• If we did try, how quickly would we decide whether it is worth continuing?
• What side effects and legal considerations should I weigh against a condition that may settle anyway?
• How will my GP and the clinician who diagnosed me stay involved?

If you want to take this further

The useful next step is a proper assessment, not a longer reading list. Gather your diagnosis, the treatments you have already tried and what happened with each, and a current list of your medicines — that is what a specialist needs in order to give you a straight answer.

The consultation itself, and what happens after it, is set out in What is the process to get a medical cannabis prescription? If meralgia paraesthetica is not the only thing you are being treated for, say so early: other conditions and other medicines change the assessment.
