What to expect from a cortisone injection for pseudogout

Pseudogout, also called calcium pyrophosphate deposition disease, can trigger sudden swelling, warmth and pain when crystals irritate a joint. A clinician may place cortisone into the joint after checking that infection is not the cause of the flare. The medicine acts locally to settle inflammation; it does not remove the crystals or prevent every future attack.

The joint may feel tender or fuller for a short time after the procedure. Improvement is not always immediate, and the response differs according to the joint involved and the severity of the flare.

Tell the clinician about diabetes, blood-thinning medicine, allergies, recent infection and any problem with previous injections. Wear clothing that allows easy access to the joint. Afterward, follow the advised rest period and avoid strenuous loading of that joint until the soreness settles.

Use the aftercare plan you were given rather than adding extra medication on your own. As movement becomes easier, gradual activity can help restore function. Keep the injection site clean and watch the skin for increasing redness or drainage.

Contact the treating service promptly if pain, swelling, warmth or redness is worsening rather than settling, or if you develop fever, chills or feel unwell. These symptoms need assessment because an infected joint can resemble a crystal flare. Seek urgent help for severe pain with inability to move the joint, new weakness, or a rapidly spreading reaction.

Ask which joint will be injected, how infection was excluded, when you may resume normal activity, and what plan will manage future pseudogout flares. If you have diabetes, ask how to monitor your glucose after the injection.
