Within the shoulder, the fluid-filled bursa sac sits between the tissues and provides cushioning. Bursitis happens when the bursa and the rotator cuff tendons get compressed between the bones of the shoulder. Left untreated, this chronic impingement can lead to fraying and eventually tearing of the rotator cuff tendons.
Poor postural awareness
Pain and weakness of shoulder muscles, especially when using the arm overhead
Limited shoulder mobility, such as trouble reaching up and behind the back
Bursitis can also appear in the hip, knee, and elbow.
Physical therapy: massage, ultrasound, interferential current, range of motion exercises
Surgery in some cases
