Excessive use or an overuse of joints can cause bursitis. Excessive use may come from prolonged pressing on a certain joint, such as from kneeling or sitting on a hard surface. It can also result from playing a sport that requires repetitive motions using a particular joint, such as the shoulder joint when throwing a baseball.Repeated bending of the elbow, e.g., while playing tennis can cause elbow bursitis while repeatedly reaching upwards or lifting overhead can cause inflammation in the shoulder.People middle-aged and older as well as athletes are more likely to be affected by bursitis due to excessive use of joints.Next
