Bursitis: Causes, Symptoms, and Treatment Options
What Is Bursitis?
Your body contains more than 140 bursae—small, fluid-filled sacs that act like cushions between bones, tendons, and muscles. These allow your joints to move smoothly without friction.
When a bursa becomes inflamed, irritated, or overused, it leads to a painful condition known as bursitis. This inflammation causes swelling, discomfort, and stiffness—often impacting your ability to move freely and without pain.
