· Overview of Bursitis

Bursitis is the inflammation of bursa, which are sac-like cavities filled with lubricating fluid (synovial), at areas where friction is likely to occur, such as where muscles or tendons pass over bony places. Inflammation may be acute or chronic.

· Symptoms of Bursitis

Acute and chronic bursitis: Localized pain and tenderness, sometimes swelling and redness, may be associated with loss of normal range of motion of that joint, and sometimes becomes reddish colored and warm.

· Possible Causes of Bursitis

Trauma, malposition of specific joint or joints above and below, chronic overuse, acute or chronic infection, calcium deposits secondary to calcium malabsorption, magnesium deficiency or localized trauma, allergies especially airborne or food, vitamin B12 malabsorption, inflammatory arthritis, gout, rheumatoid arthritis, infective organisms.

Special Note:
Most commonly affected joints are shoulder, elbow, and hip which are often referred to as "frozen", due to loss of normal range or motion.
