Bursitis is inflammation of the bursa, the fluid filled sacks that cushion points of contact between tendons, ligaments, and bones. Especially prevalent in the shoulder and knee joints, bursitis can cause pain upon movement, heat, swelling, and limited mobility. The term is often used as a general description for shoulder pain where the cause is unclear and is generally thought to occur from misuse.
From the Clinical Somatics viewpoint, the bursa would not swell to begin with, and will in fact heal more readily, if the pressure and misuse of the joint can be prevented through the relaxation of the muscles around the joint and the proper synergistic interplay of the muscles that coordinate the joint movement and the movement of the joint as it relates to the movement of the whole body.
