I used to think that I had sever heartburn but I am noticing a pain when ever I swallow food in my lower chest area. It burns and then turn into extreme pain causing me to sweat and I even have to hold my breath. I still believe I have heartburn but I may be afraid that my condition is worse than that. There is no specific food that cause the pain and antacids like pepcid do not work anymore. So my question is what could this be?
