Prevention of Shoulder Tendonitis
Because most cases of tendinitis are caused by overuse, the best treatment is prevention. It is important to avoid or modify the activities that cause the problem. Underlying conditions such as improper posture or poor technique in sports or work must be corrected.
Apply these basic rules when performing activities:
Take it slow at first and gradually build up your activity level.
Use limited force and limited repetitions.
Stop if unusual pain occurs.
