A condition commonly known as tennis elbow is pain felt on the outside of the elbow. It is due to the inflammation or minor tear of the tendons that connect the forearm muscles to the elbow.
The name, tennis elbow, suggests that it is caused by tightly gripping a racket and engaging in a back hand stroke with poor technique. However, it does not affect just tennis players. Overuse of the hands and forearm may cause inflammation or minor tear of the extensor muscles on the forearm for anybody.
