When is cortisone injection recommended for bursitis?

A bursa is a small fluid-filled sac that reduces friction near a joint. Irritation can make pressure and movement painful. Cortisone is an anti-inflammatory medicine placed near the affected bursa to reduce swelling and discomfort. It is not suitable for every swollen area: infection, bleeding risk, an unconfirmed diagnosis, or a nearby tendon problem can change the recommendation. The injection may support movement and rehabilitation, but it does not remove the activity or mechanical trigger by itself.

Tell the clinician about fever, skin infection, diabetes, blood-thinning medicine, allergies, and previous injections. Protect the area from repeated pressure while it is painful, and use the movement plan provided by your clinician or physiotherapist. After an injection, follow advice about activity and watch the site for worsening redness or heat. Learn more in [Cortisone Injection](/treatments/non-surgical-orthopedics/cortisone-injection/).

Seek prompt medical care if a painful swollen joint is hot or red, you have fever or feel unwell, or swelling and pain are rapidly worsening. Assessment is also needed after an injury that causes loss of movement, unusual deformity, or sudden weakness. These signs may indicate infection, a fracture, or another condition rather than uncomplicated bursitis.

Ask which bursa is involved, how the diagnosis was confirmed, and what non-injection options remain. Clarify whether the medicine will be placed into the bursa or beside it, how long to protect the area, and what symptoms should trigger a review.
