RAH, you probably have acid reflux.You need to get it checked out as we lost a good friend at 43 due to this. I had it bad 2 years ago and had my stomach scoped and they found a lump one in.x3in. which turned out to be stomach lymphona which has no symptons until it is usually to late. So doc. told me acid reflux helped me big time. They can't cure it but it beat back with a easy chemno.Good luck.
