Quick Answer
Carpal tunnel syndrome is the most common entrapment neuropathy — numbness/tingling in thumb, index and middle fingers, worse at night. Treatable before permanent damage.
Medically reviewed by Dr. Jitendra Prasad Yadav • NMC 8029 • Kathmandu Neurology Clinic & Cognitive Center
Carpal tunnel syndrome (CTS) occurs when the median nerve is compressed within the carpal tunnel at the wrist — a narrow passage containing tendons and the median nerve. It causes numbness, tingling, burning and pain in the thumb, index, middle and half of the ring finger — typically worse at night and with gripping activities.
Symptoms
Numbness/tingling in thumb, index, middle fingers (median nerve distribution), worse at night (waking patients), dropping objects, hand weakness in advanced cases, thenar muscle atrophy (thumb wasting) in severe cases. Symptoms often radiate to forearm.
Diagnosis
Clinical: Tinel's sign (tapping wrist reproduces symptoms), Phalen's maneuver (wrist flexion reproduces symptoms), thenar weakness/atrophy. Nerve conduction studies (NCS) confirm diagnosis and severity — most reliable test. Ultrasound can assess nerve swelling.
Treatment
Wrist splinting (especially at night) for mild cases. Activity modification, ergonomic adjustments. Corticosteroid injection for moderate cases. Surgical release (carpal tunnel release) for severe cases or those failing conservative treatment — highly effective, usually outpatient, rapid recovery.
When to seek professional evaluation
CTS is diagnosed with examination and nerve conduction studies — because treatment (splint vs injection vs surgery) depends on severity and duration.

Supplements only help when a deficiency is present; underlying cause-directed care is needed.
If the underlying cause is corrected early (e.g., improving glucose control, treating vitamin deficiency), improvement may occur. Long-standing neuropathy is often not fully reversible.
Migraine is a neurological condition; headache is one feature. Associated symptoms and functional impact are important for diagnosis.
Aura refers to visual, sensory, or speech symptoms that precede the headache in some people. Both types are migraine; the presence of aura may influence management discussion.
