I ve been experiencing achy chest pain, in the middle of my chest, on and off for about 5 months now. It comes and goes, isn t super painful, but painful enough I know it s not normal. It seems almost like a heavy sensation and then will become acute for a second and then just feel like a heavy pressure. Seems lately like I can always feel the heaviness and then from time to time it becomes acute. I feel it sometimes when I m sleeping as well as awake. Sometimes I think it s in the middle of my back and the pain is radiation out towards my sternum. I had an ECHO Cardio gram on the treadmill about 10months ago, for the same symptoms and it showed nothing. The symptoms since then went away for a few months but have been back for the last 5 months. What I m feeling can t be normal. My wife says could be stress, but I don t think I m any more stressed than I normally am and not a stressed out person by nature. Hard to describe the pain - all I can say is I can always feel the heavy presence feeling and now and again it kind of grabs me for a split second. Any thoughts?
