What is Tennis Elbow?
Tennis elbow is an inflammation around the bony
knob on the outer side of the elbow. It occurs when the tissue that attaches
muscle to the bone becomes irritated. The bony knob is called the lateral
epicondyle, and tennis elbow is also called lateral epicondylitis.
Playing a racket sport can cause tennis elbow. So can doing anything that involves extending your wrist or rotating your forearm such as twisting a screwdriver or lifting heavy objects with your palm down. With age, the tissue may become inflamed more easily.
