Bursitis in the Knee, Elbow, Hip, and Shoulder.
Bursitis can be found in the knee, elbow, hip and shoulder and is a painful condition caused by inflammation of the bursae, small fluid-filled sacs that cushion and lubricate the joints. These sacs help reduce friction between bones, tendons, and muscles, facilitating smooth movement.
When bursitis occurs, the affected bursa becomes inflamed, leading to pain, swelling, and limited mobility in the nearby joint. Common sites for bursitis include the shoulder, elbow, hip, and knee.
