What does the medical term bursitis mean?

Bursae sit where skin, tendons, or muscles move over bone. When one is repeatedly compressed, rubbed, injured, or less commonly infected, it can become painful and swollen. Symptoms depend on its location: a superficial bursa may produce a visible soft swelling, while a deeper one may cause tenderness mainly with movement or pressure. Bursitis names are usually based on the affected site, such as the shoulder, elbow, hip, or knee. Nearby tendon and joint disorders can feel similar, so location alone does not establish the diagnosis.

Initial care often focuses on removing the pressure or repeated movement that is irritating the bursa while preserving comfortable motion. Padding, activity adjustment, a wrapped cold pack, and a guided exercise plan may be useful depending on the site. Anti-inflammatory medicine requires an individual safety check because medical conditions and other medicines can alter its suitability. Aspiration may be used to examine fluid when infection or another cause is suspected, while a cortisone injection is reserved for selected non-infected cases. Neither procedure should be attempted at home.

Arrange an appointment if pain or swelling persists, repeatedly returns, restricts movement, or follows an injury. A hot, red, rapidly enlarging swelling—especially with fever, drainage, broken skin, or feeling unwell—needs prompt assessment for infection. Seek urgent help if an injured limb looks deformed, cannot take weight, becomes numb or weak, or develops a pale, blue, or cold hand or foot. These findings call for evaluation beyond routine self-care for bursitis.

Ask which bursa is affected, what may be irritating it, and whether a tendon or joint problem is also present. Useful follow-ups include which movement should be reduced, which should continue, how infection was excluded, and what finding would lead to imaging, fluid sampling, physiotherapy, or injection.
