Ulnar neuritis is inflammation of the ulnar nerve in the arm that results in numbness or weakness in the hand. Common symptoms include elbow and hand pain, elbow tenderness, numbness, and decreased grip strength. Ulnar neuritis is usually caused by repetitive motion or pressure on the elbow, where the ulnar nerve consistently rubs against the medial epicondyle. Conservative treatment includes rest, activity modification, physical therapy, and bracing. Occasionally, surgical treatment is warranted. This may include ulnar nerve decompression and transposition, which aims to reduce friction or compression on the nerve.
