Ulnar nerve compression is a nerve disorder that can cause numbness, pain, or tingling in the arm, hand, or fingers. When you bend your elbow, the ulnar nerve—which travels from the shoulder to the hand—wraps around a bony ridge on the inside of the elbow called the medial epicondyle. Keeping your elbow bent for long periods of time or repeatedly bending your elbow can irritate the nerve and cause the pain, tingling, or numbness associated with this condition.
The condition, also called cubital tunnel syndrome, most often results from the nerve being squeezed as it passes behind the elbow in the cubital tunnel, an area commonly known as the “funny bone,” a channel that allows the ulnar nerve to travel over the elbow.
