Help, How to get rid of fibrin? in Sclero Forums (MAIN) Posted December 25, 2016 Hello Paulo, Welcome to Sclero Forums! I'm sorry your father has scleroderma, and a nonhealing ulcer. Please have him call or see his doctor for further wound care instructions, if there is anything at all that seems to be impairing the healing. It is not a "do it yourself" job because the wrong approach, even if very well-meaning, can make ulcers worse, and every situation is different. It's normal to have regular doctor appointments to treat the wound, until it is entirely healed. Please let us know what you find out, and give our best wishes to your father, too.
