Thanks for the info on EE, I never heard of that before, but will look into it. He had been on Pepcid years & years ago on a daily basis, but his episodes of chest pain & vomiting are so random, it didn't seem to do anything. So he hasn't been on any meds for GERD at all in the last 8 years. He gets severe chest pains maybe once a month that can't be related to any activity or anxiety, they last anywhere from 2 -20 minutes. He goes to a Ped Cardio once a year where they did diagnose mitral valve prolapse, but that's very minor, and should not be causing the chest pain. All other cardio tests are normal. He experiences frequent (I shoudn't say frequent - maybe once a month) vomiting about an hour after he goes to sleep - that's why she suspects GERD, it's a classic symptom. It's always a once & done vomit, and he's not ill otherwise, it just seems like his food hasn't settled or digested or whatever, and when he lays down, it comes back up.
He also cannot digest orange soda - isn't that strange? He has vomited right after drinking it every single time. He can tolerate any other soda and orange-flavored things, so I have no idea where this is coming from!
I'll post back tomorrow & let you know what happens. I don't know if they will tell us anything there, or if they send the results to the doctor to go over with us.
Thanks again for everyone's information!
