Please Please please go to the doctors.
This is what happened to me and maybe you have the same thing. I went to the doctors because I could not move more then 5 feet without loosing my breath. I had to get a heart catheterization. Nothing was found and two days later I was in the same shape. I went to a different doctor ( it was a physicians assistant) and he said I had acid reflex. He said, you would not believe what that can do to you. I take prilosec and that has not happened again. I dont take it all the time only when I know Im going to eat something like tomatoes, anything spicy, sometimes lettuce does it to me. I did read where prolong use of it can cause brittle bone disease and thats why I dont take it all the time. There were times when I slept sitting up on the couch and I don't lay down to sleep I use 2 pillows. Try drinking a lot of water when you eat. Try some prilosec, it takes about a day or so to work. If it doesnt work, please Please please go to the doctors. This may sound weird but if you can burp do you feel better? I had gone to the ER 2 times with it and my BP was so high the machine kept going off. They had me stay in the hospital to watch me, they found nothing. It can give you so much pain and I have learned to walk a lot if I feel it coming on.
But it was a physicians assistant that found it, not a doctor, not the hospital.
