I have Raynauds Synd. and was never told I could have had a posion of any sort that could have caused it. I am 58 and am surprised that with all the abspestis and lead and DDT I as a child was subjected to that I haven't cancer of some sort by now! Raynauds however is a pest in itself. I have heart palps. and shortness of breath and fatigue and joint pain but not all the time. Sometimes I feel like a million bucks!! But that is short lived. I eat well and don't do and habbits that would inflame my condition. Stress, well that's another thing altoghter most of use can't avoid. How would one get test or ask their Dr. to do them? Smiles
