What is bursitis?

Bursitis is defined as the inflammation of the bursa, which are small, fluid-filled sacs located throughout the body, particularly around joints. These sacs serve as cushions between bones, tendons, and muscles, helping to reduce friction and allow for smooth movement during physical activity. When bursae become inflamed, often due to repetitive motion, injury, or prolonged pressure, it results in bursitis, characterized by pain, swelling, and limited mobility in the affected area.

This definition encompasses the key aspects of the condition, distinguishing it from other issues such as fractures, tendon injuries, or bone diseases. Understanding the role of bursae and how inflammation can impact joint function and pain management is essential for clinicians and those involved in the treatment or rehabilitation of musculoskeletal conditions.
