i would like to know what might be wrong with me...i wake up every morn feeling like i want to throw up, hardly do, if anything, it might just be some clear spit...theres no burning or anything that would suggest acid reflux...mostly i just gag, nothing brings it on...i can just be sitting, watching tv and start gagging, not eating, drinking nothing...it started few months back, around that time my stomach started harding, im not pregnant, ive talked to my doc and he was stumped...im just wondering if it might be a tumor?
