OTHER THAN A HEART ATTACK...what kinds of things could cause left sided chest discomfort? Like around the breast, and in the rib area, and a burning in the shoulder blade? Please, do NOT say Heart attack...I asked OTHER THAN A HEART ATTACK...what other things could cause this. It has been going on for around 2 months now, give or take a week. I have been to the doctor and am currently waiting test results, that I should be getting Monday, so I am looking for ideas now of what could be going on. I am 26 year old female. QUit smoking around 2 months and 3 weeks ago. Having chest soreness, and discomfort, along with some panic attacks. Occassional shortness of breath, but it isn t bad. Never lasts longer than a minute or two. Doesn t happen often. The chest soreness is there almost all the time. Activity does not increase it, infact, often times, activity helps it. Any suggestions would be appriciated! Thanks. Please don t say go to dr. ALready went.
