The ulnar nerve runs behind the medial epicondyle on the inside of the elbow. Beyond the elbow, the ulnar nerve travels under muscles on the inside of your forearm and into your hand on the side of the palm with the little finger. As the nerve enters the hand, it travels through another tunnel (Guyon's canal).
What are the symptoms of ulnar nerve damage?
Symptoms
- Abnormal sensations in the little finger and part of the ring finger, usually on the palm side.
- Weakness, loss of coordination of the fingers.
- Clawlike deformity of the hand and wrist.
- Pain, numbness, decreased sensation, tingling, or burning sensation in the areas controlled by the nerve.
Where is ulnar nerve pain felt?
The ulnar nerve is also responsible for sensation in the fourth and fifth fingers (ring and little fingers) of the hand, part of the palm and the underside of the forearm. Ulnar nerve entrapment can cause pain, numbness and tingling in the forearm and the fourth and fifth fingers.
