This is the sixth day that I have had this problem, I have never had the problem this bad. I have severe acid feeling in my stomach. Been to the doctors who gave me another antacid to take with nexium. I also have jaw pain and feel my glands are up, the doc said this sometimes can happen but dont worry its not a heartattack. I am worried so much, I have never had this awful acid feeling before and am wondering if anyone else has ever had this problem for so long. Sure I have had this before but its never lasted this long, I am going insane with the awful acid feeling
