Ayurvedic medicine for nerve pain

Nerve pain is not ordinary pain. It is a misfiring signal, and it responds badly to the painkillers people reach for first. The useful question is which nerve, and why it is misfiring.

What nerve pain feels like

• Burning, electric, shooting, or a raw feeling where the skin is not touched.
• Numbness alongside over-sensitivity, which is the odd signature of neuropathic pain: the area is dead to some things and agonised by others.
• Allodynia: bedsheets, a sock seam, or a draught hurting.
• Worse at night, which is why sleep is usually the first casualty.
• Tingling in both feet and both hands in a stocking-and-glove pattern points to a metabolic or nutritional cause. One side, one strip, one nerve points to a local problem.

The causes decide the treatment

• Diabetes is the commonest. Sugars that have run high for years, and neuropathy that is already present at diagnosis in a fair number of people.
• Vitamin B12 deficiency, extremely common in India and in vegetarians, in metformin users, and in anyone over sixty. This one is worth finding, because correcting it can genuinely help.
• Shingles, and the post-herpetic pain that follows it, sometimes for months.
• A trapped nerve: the wrist in carpal tunnel, the foot in tarsal tunnel, the leg from a disc.
• Thyroid, kidney and liver disease, and alcohol, all of which injure nerves directly.
• Chemotherapy, which leaves a numbness that may improve slowly and may not improve at all.
• Autoimmune and inflammatory neuropathies, which need a neurologist and disease-modifying treatment, not support.
• Where the cause is still active, treating the cause is the whole of the treatment. Nothing herbal outruns a sugar that stays high or a B12 that stays low.

What we prescribe

• Ashwagandha as the backbone of most nerve courses, for the pain, the sleep and the fatigue together. It is slow, and it is well tolerated.
• Bala and ksheerabala, the classical nerve tonics, as an oil externally over the painful area and, where the physician judges it appropriate, in a small internal dose.
• Guduchi where there is an inflammatory component, and in the diabetic picture alongside the metabolic work.
• Triphala, gently, because constipation from the pain medicines and from reduced activity is nearly always part of the picture.
• Nisha-amalaki, turmeric and amla, where the sugars are involved.
• Mahanarayan or balarjataila applied externally. The relief from a topical oil is real, local, and safe in a way that an extra oral tablet is not.
• Saraswatarishta or brahmi preparations where concentration and mood have been worn down by months of pain, which is a legitimate target rather than a side issue.
• Iron, B12, folate and vitamin D only where a level says they are needed. Topping up something that is not low is not treatment.

What the evidence supports

• The drugs that work for neuropathic pain are conventional: gabapentin and pregabalin, amitriptyline and nortriptyline, duloxetine, and a capsaicin or lidocaine patch for a local area. They are the first line for good reason, and we do not pretend a herbal course matches them.
• Alpha-lipoic acid has decent evidence in diabetic neuropathy and is often the most useful single addition.
• Among the herbal group, ashwagandha and bala have traditional use, animal work and small human studies behind them. That is enough to justify trying them as support and not enough to promise relief.
• Correcting a proven B12, thyroid or vitamin D deficiency can produce real improvement, and it is the intervention most often skipped.
• Nothing here reverses a nerve that has been destroyed. Regrowth is slow, partial, and sometimes impossible.

What medicine will not do

• It will not untrap a nerve that is being compressed. Carpal tunnel with night waking and then constant numbness and weak grip is a surgical question, and delay costs thenar muscle that does not come back.
• It will not restore foot drop.
• It will not fix diabetic neuropathy while the sugars stay high.
• It will not treat the pain of an inflammatory or autoimmune neuropathy, which needs the specialist drugs for that condition.
• It will not work in the first two weeks. Anyone expecting that stops a course that would have helped.

When to be seen urgently

• Numbness around the back passage or genitals, with difficulty passing urine or loss of control of bowel or bladder, or both legs going weak. That is cauda equina and it is a same-day surgical emergency.
• Weakness that is spreading upward over days, particularly after a recent infection. Guillain-Barre syndrome needs monitoring because it can reach the breathing muscles.
• Sudden one-sided numbness or weakness, facial droop, or speech that has changed. Stroke, immediately.
• A shingles rash near the eye, on the forehead, or with ear pain and facial weakness. Antivirals early change what happens next.
• Any foot that is numb, with a sore, a blister or a colour change. In a diabetic foot this is an emergency in all but name, and the difference between a dressing and an operation is usually a matter of days.
• Unexplained weight loss with nerve pain, pain that wakes a person from sleep with no other reason, or a known cancer.

The daily part

• Inspecting both feet every day if they are numb. Not weekly. Every day.
• Shoes that fit, no walking barefoot, and no hot-water bottles on an area that cannot feel heat.
• Sleep protected, because pain tolerance and sleep have a two-way relationship.
• Movement that the nerves permit, since deconditioning and stiffness become their own problem within weeks.
• Alcohol reduced, because it is both a cause and, at the level some people drink, a reason a course cannot work.
• Sugars, blood pressure and lipids controlled, which is how the remaining nerve fibres are protected.

How we judge it

• Nights of undisturbed sleep, and how much of the day the pain is out of the way.
• Whether the topical and the oral support have let the conventional dose come down, which is a fair and realistic goal.
• A review at six to eight weeks. If a nerve that is not improving has not been imaged, tested or referred by then, that is the next step rather than another bottle.
• And honestly: with neuropathic pain, a good result is often less pain and more function, not none. Anyone promising a cure is not the person to trust with a nerve.
