What to expect from steroid injection for granuloma annulare

A clinician examines the ring-shaped bumps or patches and chooses lesions that are suitable for local treatment. A small amount of corticosteroid is placed within the affected skin. The aim is to lessen inflammation in that spot, so changes usually develop over time rather than appearing immediately.

You may notice a brief sting, followed by mild tenderness or redness. Lesions may become flatter or less noticeable as they respond. Granuloma annulare can affect more than one area, and one treated lesion does not necessarily represent the behaviour of every patch. The clinician may therefore discuss observation or other treatments as well.

Before treatment, mention skin infections, allergies, diabetes, medicines that affect immunity, and any history of a dent or colour change after steroid injections. After treatment, keep the area clean, avoid picking at it, and follow instructions about covering or washing the site.

Watch the lesion without repeatedly pressing it. A temporary lighter patch, local skin thinning, or a small indentation can occur. If the area is exposed, ask which sun-protection method is appropriate for your skin. Do not use strong creams on the injection site unless your clinician has included them in the plan.

Contact the clinic if the treated area becomes increasingly hot, swollen, painful, or draining, or if you develop fever. Seek urgent assessment for rapidly spreading redness or severe pain. Arrange a review if the lesion changes in an unexpected way, the skin becomes noticeably indented, or new patches appear and need a fresh diagnosis or treatment discussion.

Which lesions are appropriate for injection, and what change should I look for? How long should tenderness last? What is the plan if other patches appear? Could my skin colour or texture change at the injection site, and how would we manage that?
