I have limited systemic sclerosis. New terminology for CREST. I was just contacted by a research tech from Mayo in Rochester to participate in a GI study related to scleroderma. If you go on the Mayo Clinic .org site under clinical trials. I am really glad to be doing this. Not that I will learn anything new about my illness. Unless there is something significant they report back to me. But because there is so little information and research out there related to scleroderma. Hopefully it will help the next person.
