Tennis elbow is an inflammation of the tendons that join the muscles of the forearm to the outside of the elbow. It often occurs due to overusing the forearm muscles and tendons and those around the elbow joint.
Tennis elbow is also known as lateral elbow pain or lateral epicondylitis and is not necessarily related to tennis. However, tennis players often develop the condition because it stems from repetitive muscle use. Half of all tennis players will get tennis elbow in their career.
Tennis elbow is thought to affect between 1 and 3 percent of the population in the United States (U.S.). It usually occurs between the ages of 30 and 50 years.

This is normally enough information for tennis elbow diagnosis.
An MRI gives a more detailed image than an X-ray, as it includes the soft tissues, muscles, and tendons inside the arm. This may be required if the outer elbow pain does not respond to conservative treatment after a year.
Electromyography (EMG) may be used to find out if the nerves are compressed.
Several treatment methods can be used at home or after consulting a physician.
