Symptoms of Cubital Tunnel Syndrome
In patients with cubital tunnel syndrome, the ulnar nerve is pinched in one of several locations in the back of the elbow. Common symptoms of cubital tunnel syndrome include:

Pain, tingling, and numbness in the small and ring fingers. These are often called pins and needles symptoms.
Weakness of the muscles in the hand.
Symptoms may be felt when you have your elbow bend for a long time.

These weakened muscles, called the intrinsic muscles of the hand, help with finger movements. Patients with more severe symptoms of cubital tunnel syndrome may experience a tendency to drop objects or have difficulty with fine movements of the fingers.
