Tennis Elbow: Symptom and Causes

Symptoms

The most common symptom is pain and tenderness on the outside of your elbow and in the muscles of your forearm.
Pain may get worse when you:

• grip something, for example holding a pen or shaking someones hand
• twist your forearm, for example turning a door handle
• use your keyboard or mouse
• fully extend your arm

Causes

Tennis elbow is usually caused by overuse of the muscles attached to your elbow and used to straighten your wrist. Any activity that involves repetitive twisting of the wrist (like using a screwdriver) can lead to this condition. Therefore, painters, plumbers, construction workers, cooks, and butchers are all more likely to develop tennis elbow. This injury is common in people who play a lot of tennis or other racquet sports, hence the name "tennis elbow."
