Hello, this is very good to read for me i have had exactly the same its a coincidence (or is it) that i have had GERD well i do seem to have it and am taking pills which have really helped only started two days ago my chest pains and shortness of breath are present still, have you had people say oh it must be anxiety and doctors give you stupid excuses ...its muscular/plueracy/skeletol go home a rest and in 2 day syou will feel fine 3 months later my chest pains are here, anyway my tests all came back perfect aswell im 22 perfect weight never smoke dont drink excessively etc etc, i do have asthma and i think GERD may flair this up and ive read Gerd can reproduce symptoms not disimalar to angina, my pain tends to be around the wall of the chest which does suggest more asthmatic related rather than heart also no left arm problems/dizziness etc,
