I think I might have gerd I went to the ER a week ago with chest pains below my breast bone, stomach pain, chills, sweats etc. I was giving a prescrition for Priolosec (OTC). That had been my second attack. I have had a total of three so far any my last one was today. I woke up at 6:45 with burning inscruciating pain bewteen my chest and below my breast bone. The pain remain servere until 2pm today. I call them attacks at this point. They havebeen debilataing and seem to last for several hours. Any similiar problems out there. Howlong would an acid reflux attack last.
