The ulnar nerve runs along the ulna bone in the arm. It starts at the shoulder and ends at the pinky finger.
"In human anatomy, the ulnar nerve is a nerve which runs near the ulna bone. The ulnar collateral ligament of elbow joint is in relation with the ulnar nerve." -

The answer truly depends on the severity of the ulnar entrapment and the location of the ulnar nerve entrapment. Milder ulnar nerve entrapments can sometimes be relieved with physical therapy and bracing the arm in a position that lessens pressure on the ulnar nerve. Moderate entrapments of the ulnar nerve may respond to physical therapy combined with a steroid injection to relieve inflammation. More severe entrapments may require surgical interventions. The most common location for an ulnar nerve entrapment is at the elbow, this is called an ulnar neuropathy at the elbow (UNE). When this is severe the surgical procedure that is utilized is referred to as a surgical transposition of the ulnar nerve & involves moving the ulnar nerve from the back of the elbow to the front of the elbow. Speak with a neuromuscular specialist regarding your case if you feel that you have an ulnar entrapment, and always keep in mind that you may want to get a second opinion. Be prepared for the possibility of an electrodiagnostic examination. This test would help determine if ulnar nerve is involved, where along the ulnar nerve the lesion is, & how severe the ulnar nerve lesion is.
Sure. The ulnar nerve begins at the brachial plexus ... which is in your arm-pit.

Most commonly, trauma to the elbow or repetitive bending of the elbow puts pressure on the ulnar nerve that damages the myelin sheath insulating and protecting the nerve.
The median nerve supplies most of the flexor muscles of the human forearm, and some hand muscles. The ulnar nerve also supplies two flexor muscles, and most of the remaining hand muscles that the median nerve does not cover.
