Golfer's elbow is one of the most common golf injuries. Technically called "medial epicondylitis," it is an inflammation of the tendons that attach our forearm muscles to the bone on the inside of our elbow. Pain and tenderness are usually felt on the inner side of the elbow, but may also spread to the forearm and wrist.
The condition, which can also develop in people who have never swung a golf club, usually results from overuse. Repeating the same motion over and over again, such as swinging a golf club, puts strain on the muscles and tendons.
Golfer's elbow is most common in the right elbow of a right-handed novice golfer. Those who develop the condition often have a poor weight shift and tend to throw the club down at the ball. This is sometimes referred to as "hitting from the top." This can increase the stress at ball impact on the muscles on the inside of the forearm. There is increased muscle activation of the pronator teres, an inner forearm muscle, specifically during the acceleration phase of the swing. Transferring your weight smoothly from your back to your front foot with your shoulders level will ensure proper contact of the club face with the ball.
Golfer's elbow can also develop in the left arm of a right-handed golfer if follow through is created by turning over the wrist. In these cases, there is increased strain on the inside of the left elbow as the golfer's wrist turns palm up.
