Causes: Tennis elbow is a condition brought on by the overuse of arm, forearm and hand muscles. It refers to an injury of the muscle and tendon area around the outside of the elbow. Of course, it often affects tennis players with poor backhand technique, but doing several other things that ask a lot of the muscles in question can also bring about the condition.
Rehab Tips: First and foremost, start with rest. According to Camp, it’s important to let the muscles and tendons heal on their own, and exercises to get your arm back in working form involve strengthening the opposing muscles by doing a series of different forearm workout routines.
