I have a strange hollow sensation in my chest. It comes and goes with no other real significant symptoms. My mother has GERD and I think I might, too. I run a lot, don t smoke, drink coffee, am stressed and anxious quite often. I think if it were a heart attack, I d be dead by now, because this hollow sensation has come and gone for years in varying intensities. Sometimes I feel like I ve got a lump in my throat.
