According to Dr. John Meade of OrthoCarolina Monroe, bursitis presents as a large, soft knot on the knee or elbow. Most cases are mechanical, resulting from minor or repetitive trauma often after a bump or fall.
Physically demanding jobs and hobbies, like football or roofing, put you at risk.
Cases typically resolve on their own with rest and protection. Seek medical treatment if they prove inconvenient or uncomfortable.
