What is bursitis?

Bursitis is the inflammation of a bursa, which is a small, fluid-filled sac that provides cushioning and reduces friction between tissues such as bones, tendons, and muscles near joints. The bursa plays a crucial role in facilitating smooth movement and reducing wear and tear during physical activity. When bursitis occurs, this normal function is disrupted due to inflammation, leading to pain and discomfort in the affected area.

Understanding this condition is important for effective patient care, as it can often be confused with other musculoskeletal issues. For instance, while tendon inflammation (tendinitis) involves the tendons and can cause pain and swelling, it is distinct from bursitis, which specifically involves the bursa. Similarly, joint infections and cartilage degeneration affect different structures within the joint and have different treatment approaches. Recognizing that bursitis is strictly about the inflammation of the bursa is essential for accurate diagnosis and management of joint-related issues.
