Cubital Tunnel Syndrome

Cubital tunnel syndrome -- also known as ulnar neuropathy -- is caused by increased pressure on the ulnar nerve, which passes close to the skin's surface in the area of the elbow commonly known as the "funny bone." You're more likely to develop cubital tunnel syndrome if you repeatedly lean on your elbow or bend your elbow for sustained periods, such as while talking on the cell phone or sleeping with your hand crooked under your pillow. In addition, sometimes cubital tunnel syndrome results from abnormal bone growth in the elbow or from abnormal bone growth in the elbow or from intense physical activity that increases pressure on the ulnar nerve.

Early symptoms of cubital tunnel syndrome include:

  • Pain and numbness in the elbow

  • Tingling, especially in the ring and little fingers
