Hello, I am a 26 year old male. When I was 14, I got a very weird and hard-to-describe spasm/pain/discomfort in my chest and middle back area. At the time I was convinced it was a heart attack, i felt like i was dying or rotting inside. It has come and gone hundreds of times since then but it is definitely getting more frequent, more intense and more unbareable. The pain is right between the chest and back, so much that I sometimes think it s related to my lungs (I have really under-control asthma). However, it also affects my jaws, mostly the right side. The worst part of this discomfort is feeling like there is some type of acid or boiling water travelling from my back to my chest to my jaws and I swear I can sometimes feel the bubbling of said acid right under my tongue on the right side. I find myself pushing against the back of my jaw with my thumb to relieve pressure. What I discovered with time is that COLD WATER helps a whole lot! Sometimes making me better and other times completely getting rid of the pain. I am worried that this is something serious however my Doc and several others I tried ro explain this to brush this off and call it something muscular and that I should be a little less stressed. I can feel that it has nothing to do with muscles. Any help?
