Ok, thanks. Good to know and maybe just a one time thing what happened to me. I was on antibiotics about a week before I flew. I didn't feel good the day I had to fly. Upon decending I got huge acid reflux which I have never had acid reflux so of course I thought I was having a heart attack. The acid reflux last about 4 days and then I got it mild on the flight back home. Went away for two week but I have been dealing with for the last two months. The doctor's think the antibiotic triggered but didn't know what to say why it happened on both flights. Hopefully just a fluk as I like to travel. Now I just need to get this acid reflux under control! Getting my scope done in a couple weeks and will see the specialist then. Thanks.
