I have been having neck and shoulder pain during activities, almost like a heart attack, have had all the work up for heart with all being good.
I first thought it was anxiety, but it seems to happen a lot, and during activities, even jusy walking
I am wondering, maybe o2 sat is low or something else, I do have Reynauds disease, but this is new, should I concider I may have scleroderma or what?
