When is cortisone injection recommended for pseudogout?

Pseudogout, also called calcium pyrophosphate deposition disease, can make a joint suddenly swollen, warm and tender. Cortisone is placed into the inflamed joint to calm local inflammation. It does not remove the crystal deposits or prevent every future flare. A clinician may first examine the joint and sometimes test joint fluid, because infection can look similar and needs different treatment.

Tell the clinician about diabetes, blood-thinning medicine, an allergy, fever or a skin infection near the injection site. Rest the treated joint briefly after the procedure, then return to gentle movement as advised. Keep the area clean and watch whether swelling and pain begin to settle. Do not rely on an injection as a substitute for assessing repeated attacks, which may need a longer-term plan.

Seek urgent medical assessment for a hot, swollen joint with fever, chills, feeling faint or rapidly worsening pain. These features can signal a joint infection, even when pseudogout is also possible. Contact the treating clinic if redness spreads, drainage appears, or pain becomes markedly worse after the injection.

Ask whether the joint should be tested before injection, what improvement to expect, how long to protect the area, and which medicines or conditions could affect the decision.
