Patient: I get tighten in my chest alot, canwalk up 12 stairs and get out of breath, shorten of breath doing normal chores around house. Sometimes chest feel like a horse is sitting ontop of it. Sitting here typing, my chest is tight now and I haven’t done anything. I havehad several x-rays and connected to see if I was having a heart attack. What do you think this is? Ifthis is asthma, why do I feel this shortness of breath so much?
