Tennis Elbow

"Tennis elbow" is a layman's term for pain on the lateral, or outside part of the elbow, on or near the bony protrusion. Tennis elbow is caused when the tendon from the elbow bone tears or is ruptured. In addition, tennis players are in constant motion, and the repeated twisting and trunk rotations can cause injuries. Shoulder injuries and turned ankles and knees also are common. The act of serving the ball also has been shown to hyperextend the lower back, and possibly compresses discs.
