I also have e. nodosum. I had an outbreak about 3 years ago. My regular doctor did not know what it was so she put me on a steriod - - wrong idea!!! That made my immune system week and the e. nododum ran wild. I was tested for eveything under the sun. About 25k worth. It finally went away. Though we are not sure why because I was on several different medications. I again broke out over the weekend. My dermatologist (who "healed" me before) put me on penicillin and asprin. He is positive it is e. nodosum but, not sure what is making it blossum. Please keep me posted.
