The short answer
Bursitis is inflammation of a fluid-filled cushion near a joint. It can cause local pain, tenderness and swelling. The location and cause matter, and a hot swollen area with fever needs prompt assessment.
Understanding the problem
Bursae help tissues move smoothly. Repeated pressure or activity can irritate them, but infection is another possibility in some cases. Pain around a joint may also arise from tendons or the joint itself. An examination helps separate these explanations.
Care and next steps
Treatment may include modifying the provoking activity, suitable pain relief and addressing the cause. Some cases need further investigation or a procedure. An injection should follow a diagnosis rather than be treated as a general remedy for any painful swelling.
Prepare for your consultation
Point out the exact tender area and describe pressure from kneeling, leaning or repeated movement. Note whether there has been a skin wound, redness or fever. Bring details of previous treatment and any recurrence. Ask what you can change at work or during exercise, when to review progress and which symptoms would require urgent attention. These details help avoid repeatedly treating a label without understanding the cause.
Common questions
Can bursitis be caused by infection?
Yes. Fever, marked heat or worsening swelling needs prompt assessment rather than routine self-treatment.
