What is tennis elbow
As the diagram above shows a large number of forearm muscles are attached to a small bony bump at the side of your elbow called the lateral epicondyle. With so many muscles attached to such a small area it creates an area of high stress. If the muscles are overused the attachment can become inflamed or injured. With the bony bump called the lateral epicondyle the condition is called lateral epicondylitis, but because it is common in tennis players the common name is tennis elbow.
Signs and Symptoms
There will be pain and tenderness at the outside of the elbow. Pain will be brought on by activities that work the muscles at the back of your forearms, such as gripping or twisting. Although called tennis elbow, it is common in people who do any sort of repetitive activity using their forearm muscles. Examples include: trades people, production workers, and those who use keyboards.
