I am 16 years old, in pretty good health, average weight, etc. I was diagnosed with GERD and a hiatal hernia about a year ago.. i've been on prevacid since December and it isn't helping. I wake up sometimes feeling as though I can't breathe. Lately, my heart feels as though it's racing from not being about to breathe, but that could be me just being scared about it. I hate suffereing from this.. it's so bad. I need to make another appointment with my specialist soon to get things in check again. I've tried tums, prevacid, prilosec, gas ex, etc. Nothing seems to be helping my condition! I'm a pretty healthy eater, a little junk here and there(but who doesnt?) HELP!
