was told that i have that too on top of the scleroderma, its an overlap of the scleroderma, but that doesnt really help me understand, ive read some links supplied by the members, but i just get lost in it, i would like just a plain old fashion explanation of it and what it does, and if theres bad id like to know that to. the doctor explained fast but not efficiently which leaves me frustrated so any words from the members? thank you
