Radial Tunnel Syndrome

Radial tunnel syndrome, the radial nerve is pinched when passing through a tunnel near the elbow. The symptoms of radial tunnel syndrome are very similar to the symptoms of tennis elbow.

Radial tunnel syndrome may cause a dull pain or fatigue in the muscles of the forearm. Nerve pressure inside the radial tunnel leads to weakness in the muscles on the back of the forearm and wrist, making it difficult to steady the wrist when grasping and lifting. It can even lead to wrist “drop,” meaning the back of the hand can’t be raised.

Symptoms of radial tunnel syndrome:

  • Tenderness and pain on the outside of the elbow.
  • Pain near the bony point on the outside of your elbow joint (lateral epicondyle).
  • Pain is worsen when one bends the wrist backward, upward, or hold something with a stiff wrist or straightened elbow.
