What Is Erythema Nodosum?
5. How Is Erythema Nodosum Diagnosed?
Veteran doctors who are familiar with the condition may be able to diagnose it on sight. Others, especially doctors who have never seen EN in person, may suggest a biopsy and bloodwork to confirm the diagnosis, or they might refer you to a rheumatologist for an expert second opinion.
Your doctor may also go through your medical history with you. He or she will want to know if you have been ill recently or taken any new medications. If you suspect that your EN was triggered by a new medication, be sure to bring it or its bottle with you.
