Tennis elbow is a condition that causes pain around the outside of the elbow. It’s clinically known as lateral epicondylitis.
It often occurs after strenuous overuse of the muscles and tendons of the forearm, near the elbow joint.

Tennis elbow is a self-limiting condition, which means it will eventually get better without treatment.

However, it can often last for several weeks or months, because tendons heal slowly. In some cases, tennis elbow can persist for more than a year.
