What Is Erythema Nodosum?
3. Who Gets Erythema Nodosum?
EN is more common in patients with underlying autoimmune conditions like Crohn’s or ulcerative colitis, but it can also appear at random in otherwise healthy people. Some EN patients have reported a flare-up of the condition after using a new antibiotic like penicillin or after successfully fighting off tuberculosis.
It’s unclear as to whether COVID-19 can trigger EN, but there have been unofficial reports of post-COVID patients who have developed EN-like symptoms. The bottom line is that almost anyone can be affected by this irritating and painful condition.
