I HAVE HAD SHORTNESS OF BREATH FROM THE SLIGHTEST EXERTION I.E. WALKING TO MAILBOX,TAKING CLOTHES OUT OF DRYER, ETC. THIS HAS BEEN going on for several years and has progressively gotten worse i also have pain in neck and jaw. i have had the echo cardigram and the angiogram as well as bloodwork. all of it was absolutely normal. where do i go from here? i am depressed i know i should be happy that everything is normal but im not "normal" and without finding anything wrong the doctors are unable to fix me. and i continue to suffer :(
