What is Cubital Tunnel Syndrome

Cubital Tunnel Syndrome, also known as Ulnar Nerve Entrapment, is when the ulnar nerve located in the arm becomes compressed and irritated. The ulnar nerve is one of the three main nerves in your arm. It travels from your neck down to your hand and can be constricted in many places, including in the collarbone or at the wrist. This syndrome occurs when the nerve is compressed inside part of the elbow.
