question: Hi...I ve been having a kind of tight feeling in my chest, kind of like squeezing, and it makes kind of a reaction of a cough, and my heart races. I ve had EKG, Echo and they were all fine. I am 52 y/o female, overweight, with Limb Girdle MD, so am pretty sedentary, but do walk in my home using a walker. Do my own cooking and laundry, and small other things. My email address is YYYY@YYYY ......................0
