When should you worry about joint swelling if you have bursitis?

A bursa is a small fluid-filled cushion near a joint. Irritation can cause a local, soft swelling and tenderness, especially after repeated pressure or overuse. The swelling may sit over the elbow, knee, hip, shoulder, or another pressure point and may hurt when that area is touched or moved. Widespread swelling, deep joint pain, or a sudden change may have a cause other than uncomplicated bursitis.

Reduce pressure and repetitive activity on the affected area, and use gentle movement rather than keeping the joint completely still. Protect the area from direct kneeling or leaning, and follow any clinician advice about ice, pain relief, or rehabilitation. Monitor size, warmth, colour, pain, and movement. Arrange a review if swelling persists, returns often, or prevents normal use.

Seek prompt care if the swelling becomes hot, red, rapidly larger, or extremely painful, particularly with fever, chills, drainage, or feeling unwell. Urgent assessment is also needed after an injury with inability to move the joint or use the limb. Do not puncture or drain the swelling yourself, because this can introduce infection.

Ask whether the swelling is in a bursa or the joint itself, what activities may be aggravating it, and how to protect the area while it settles. Ask which changes suggest infection and whether you need examination, fluid testing, or physiotherapy.
