Tennis or Golfer's Elbow?

Tennis Elbow (lateral epicondylitis) is inflammation in your lateral (outside) epicondyle and is an overuse or repetitive trauma injury of the wrist extensor muscle tendons.  Acute pain will occur on the outside of your elbow when you extend your arm as well as in your wrist with extension or gripping movements.

Golfer's Elbow (medial epicondylitis) is inflammation in your medial (inside) epicondyle and is an overuse or repetitive trauma injury of the wrist flexor muscle tendons.  Acute pain will occur on the inside of your elbow when you flex your arm as well as when you grasp something causing you to have a weak grip.

Pain for both will diminish with rest, but will get worse if not addressed.  If you have night or early morning pain/burning in your wrist, loss of grip strength to the point of dropping objects, numbness or tingling in the palm, thumb, index, and middle fingers, then you might rather have Carpal Tunnel Syndrome.
