What is it?
Tennis elbow is when the bony knob on the outer side of the elbow is inflamed. This occurs when the tissue that attaches muscle to the bone becomes irritated. Playing a racket sport can cause this injury. Also, doing anything that involves extending your wrist or rotating your forearm, like twisting a screwdriver, can cause pain.
- Pain on the outer side of the elbow and down the forearm.
- Swelling, redness or feel warm to the touch.
- It may hurt to grip things, turn your hand, or swing your arm.
