Signs & Symptoms of Carpal Tunnel Syndrome

Compression of the median nerve due to carpal tunnel syndrome can cause:

Numbness, pain, and paresthesia (‘pins and needles’) along the cutaneous distribution of the median nerve – the thumb, the palmar aspect and the tops of the dorsum of the index finger and middle finger, and half of the ring finger.

Muscle weakness, burning sensation, and cramping may also occur in the thenar muscles and first two lumbricals, causing an inability to flex the fingers and flex, extend, abduct and oppose the thumb, making it difficult to grip items, hold a pen, etc.

In chronic cases, muscle atrophy around the thumb may also occur.
