Tennis elbow is a condition that causes pain around the outside of the elbow.

It’s clinically known as lateral epicondylitis.

It often happens after overuse or repeated action of the muscles of the forearm, near the elbow joint or after banging or knocking your elbow.

If the muscles in your forearm are strained, tiny tears and inflammation can develop near the bony lump (lateral epicondyle) on the outside of your elbow.

The use of a brace, strapping, support bandage or splint (called an orthosis) may also be recommended in the short term.
