My son got erythema nodosum last year. His GI said that it was an external symptom of what was happening on the inside, and in fact his sed rate was over 100 at the time. He was put on prednisone and the pain from the bumps went away fairly quickly. However, it did take a LONG time for the bruising to go away.
