This is one of the more common things you could have with bursitis. In fact, many people experience this symptom when they first notice they have bursitis. Swelling can be caused from a number of factors, but it is usually a result of fluid being filled into the sac area. When this happens, your bursa sac begins to expand and cause problems in the joint space. Consider seeking the advice from a doctor, sports doctor, or physical therapist if you notice that your shoulders, hips, knees, or other joints become swollen. With proper care from a professional, your swelling can certainly be managed in an easy manner.
