Hi all. I have been under tremendous stress the last couple of months, really bad the last couple of weeks, but it is subsiding. I have been having these spasm feelings in the chest area, mainly around the colarbone but sometimes in the center of my chest, plus periods that last about an hour where I feel like my chest is really tight. I have been to the ER twice with this and all was normal. I had a heart stress test and all that done about 2 months ago. In between these periods, my chest muscles, collarbone, under arms, sides of breasts, breasts, between shoulder blades are all sore to the touch. What is this that's going on, realatively new for me. The chest tighness really scares me because I think I am having a heart attack. I had a friend that had a heart attack and am now pretty scared, he was overweight, smoked a lot, didn't exercise but did have anxiety. I am 33, female, smoke less than 1 pack per day, fairly active but extremely anxious. I burp a lot and they put me on Prilosec, which does seem to help with the tightness. I am scared I am going to give myself a heart attack. I am really scared when this happens. I am in therapy, but during high times of stress, I dont know to handle this!
