How are you doing now? I am spending most of my day on the couch because of the pain. I just read that new studies show that erythromelalgia may possibly be "a syndrome of dysfunctional vascular dynamics", so the pentoxifylline may just work for you. I just wanted to know who prescribed this for you, and is it helping to relieve your pain? Did you go to the mayo clinic? I think I might ask my primary for this to see if it will work. Stay strong. I hope you are finding some relief.
