Tennis elbow (lateral epicondylitis) is a painful condition that occurs when tendons in your elbow are overloaded, usually by repetitive motions of the wrist and arm.
Despite its name, athletes aren't the only people who develop tennis elbow. People whose jobs feature the types of motions that can lead to tennis elbow include plumbers, painters, carpenters and butchers.
The pain of tennis elbow occurs primarily where the tendons of your forearm muscles attach to a bony bump on the outside of your elbow. Pain can also spread into your forearm and wrist.
The pain associated with tennis elbow may radiate from the outside of your elbow into your forearm and wrist. Pain and weakness may make it difficult to:
Tennis elbow is an overuse and muscle strain injury. The cause is repeated contraction of the forearm muscles that you use to straighten and raise your hand and wrist.
