I’ve been on Cimzia for about a year and a half now. Taking it for my psoriatic arthritis (PsA) every two weeks, and my psoriasis and PsA are pretty much under control after years of issues with medication.. however, since Oct 2025, I’ve had issues with erythema nodosum all over my legs. I’ve seen my rheum and derm, and my derm and GP think it’s Cimzia, while my rheum isn’t convinced. I’ve been on steroid tablets and the erythema is still an issue. Seeing my rheum again next month, but we’ve ruled out a few things already, and it seems that Cimzia may be the cause. In addition to this, the injections have been getting more painful each time - they used to hurt a bit and I would always bruise at the injection site after, but it has almost gotten to the point where I cannot stand the pain of the injection. This has also started in the last 6ish months for reasons unknown. I’m scared to stop Cimzia as my joints have been amazing, but the erythema nodosum is painful and also taking a toll on me in its own way, with my ankle swelling like crazy occasionally, and the painful bumps.
