It is caused by strong gripping combined with repetitive motions of the wrist. A wide range of athletes experience this injury, it is not limited to tennis players. Interestingly, golfers seem to get this in their leading elbows, that is, left elbow for right-handed players and vice versa. It is also common in people whose jobs involve repetitive wrist and elbow motions, such as drivers, factory workers, and even housewives. It is characterized by pain on the outside of the elbow during movements of the wrist (ex. shaking hands or opening doors). Treatment includes ice, rest or a decrease in the activities that irritate the injury, stretching and strengthening the wrist muscles.
