I'm almost 27 and was diagnosised with GERD at the beginning of 09. I've had my stomach scope, ultrasound of my gall bladder, HIDA scan, gastric emptying study, tubeless enterlysis and all tests came back normal. But my stomach constantly burns in spite of the diet change and meds(prilosec or acidphx, activated charcoal, tums). I'm also naseaus after bowel movements or diarrhea(whichever comes first).
