Peripheral Nerve Disorders

Carpal Tunnel Syndrome

A numbness and tingling of the hand and arm that is caused by a pinched nerve at the wrist

Carpal tunnel syndrome can cause tingling, numbness, weakness, or pain in the fingers or hand; some complain of pain in the arm between the elbow and hand. Symptoms most often occur in the thumb, index finger, middle finger, and half of the ring finger. If you have problems with your other fingers but your little finger is fine, this may be a sign that you have carpal tunnel syndrome because a different nerve leads to the pinkie.

Ulnar Nerve Entrapment

Occurs when the ulnar nerve which travels from the neck to the hand becomes pinched somewhere along the way- most commonly at the elbow or wrist

Characteristics of a problem with the ulnar nerve include weakness or tenderness in the hand, tingling in the palm and ring and pinkie fingers, sensitivity to cold, and tenderness in the elbow joint.
