​Bursitis

Bursitis is the inflammation of the bursa. Bursa is a fluid filled sac, similar to a water balloon that provides a cushion between the bones, tendons and muscles in a joint (the point where two bones meet).

Multiple bursae are located all over your body near joints, commonly around your shoulders, elbows, hips and knees. Their function is to reduce friction between internal structures like muscles, tendons and bones on movement.

Bursitis is usually caused by the overuse of muscular joints, injury and very rarely, infections. Activities consisting of repetitive motions and positions can irritate the bursa. Some familiar examples of extended kneeling or prolonged leaning on your elbows are gardening, shovelling, scrubbing, carpet laying, raking, carpentry, playing a musical instrument and painting. Sportive pursuits like golf, tennis, throwing and pitching in baseball can also produce an impact.

Anyone can develop bursitis, but respective occupations and recreational activities, certain diseases (namely gout, rheumatoid arthritis, psoriasis) and older age, can increase your risk.
