I was able to speak to a nurse at the Red Cross who looked up my condition. She said that it is OK to donate blood as long as there is no localized scleroderma at the sight where they take the blood (arm). If anyone hears of contrary advice from experts please post.
I have been a blood donor but have recently been diagnosed with Morphea (on my scalp only, for now). I asked the Red Cross if I should stop donating blood but they never responded. If anyone can answer my question or even suggest someplace else for me to pose this question I would appreciate it.
