Similar to tennis elbow, golfer's elbow does not occur only in golfers. Rather, it is due to overuse of the wrist flexor muscles (i.e. muscles that bend the wrist upward with palm facing up). This can occur with squash, tennis and golf players, but can also occur in anyone who does repetitive wrist movements.
You may experience aching pain in the forearm muscles close to the elbow as well as pain on pressing on the inner bony prominence of the elbow. Pain may increase when bending the wrist down.
