Hello! I have been having bouts of IBS from time to time. IN the last 2 - 3 weeks I have been having upper left chest pain sometimes feeling like a muscular pain, sometimes a bone pain, sometimes like a burning sensation. Location of pain is not precise but always in upper left chest. I get anxious thinking its heart related but doctors think it isn't from past tests.Anyway sometimes I get lots of burping and pressure in the stomach along with the chest pain, hence I feel the chest pain has to do with IBS and likely gas.My question is, if the chest pain is gas related, shouldn't something like TUMS, Zantac or any anti-acid solve the issue within a relatively short while? I take anti acids, sometimes I feel a little better but not for long and the chest pain though is not severe it never really goes away.
