What to expect from a cortisone injection for bursitis

A bursa is a small fluid-filled sac that helps tissues glide. Bursitis may cause local tenderness, aching and pain with pressure or movement. The clinician first checks whether the pain fits an inflamed bursa and whether infection, injury or a nearby joint problem could be involved. The injection combines a corticosteroid with a local anaesthetic in some cases. Numbing may be brief; the anti-inflammatory effect can take several days. Temporary soreness or a flushed feeling may follow.

Share your medical history, current medicines, diabetes status, allergies and any skin infection near the proposed site. Avoid pressing or repeatedly testing the area after the procedure. Use the clinician’s advice about rest, cold packs and bathing. As tenderness settles, modify the movement or pressure that provoked the bursa, then rebuild strength and mobility with physiotherapy when appropriate. A cushioned surface, altered workstation or improved movement technique may reduce repeated friction, depending on the body region involved.

Get prompt medical advice if the injection site becomes increasingly red, hot, swollen or draining, or if you develop fever or escalating pain. Seek urgent care for breathing trouble, facial swelling, widespread rash, sudden weakness or severe pain after an injury. Persistent symptoms may need a review of the diagnosis and treatment plan, particularly if the bursa could be infected or if a structural problem is contributing.

Which bursa is involved, and what findings support that diagnosis? Should infection be excluded before injection? How long should I avoid pressure or repetitive loading? What change in symptoms would mean the injection has not helped?
