Condition
Carpal tunnel syndrome
Compression of the median nerve at the wrist, causing numbness, tingling, and pain in the thumb, index, and middle fingers — often worse at night.
See a clinician
Some causes of carpal tunnel syndrome need medical care, not self-treatment. Seek help for any of these:
- Constant (rather than intermittent) numbness, or wasting/weakness of the muscle at the base of the thumb — signs of nerve damage that usually need surgical assessment.
- Frequently dropping objects or losing fine motor control.
- Symptoms that progressively worsen or fail to improve with splinting and activity changes over several weeks.
- Numbness spreading beyond the median-nerve fingers, or neck pain radiating down the arm — may point to another cause needing evaluation.
What may help
Remedies studied for carpal tunnel syndrome, ranked by strength of evidence.
- C Alpha-lipoic acid supplement
Small, mostly perioperative trials are mixed — ALA may reduce post-surgical pain but does not reliably improve nerve conduction.
- D Vitamin B6 nutrient
Long promoted for carpal tunnel, but controlled trials and a Cochrane review found no benefit on symptoms or nerve conduction.
The first-line measures with the best evidence are night splinting and activity modification (and, for confirmed severe cases, surgery). Supplements have a weak record here: vitamin B6 — long promoted — has not held up in controlled trials, and alpha-lipoic acid shows only modest, mostly perioperative benefit.
