Hi i'm suffering from pressure built up in the stomach constantly i went 3 weeks drinking water and eating a normal diet and it got worse. then when i belch or burp i have to sit up or i puke it's really painful a lot of times when i burp but if i have a little sugar the pain goes down. if i eat anything no matter what it is once a week or twice a week i'll puke as if from instinct and its usually during the week i just get nauseous and have to let it out with no prior warning i'm living a nightmare and then right where my Uvula is there feels like swelling constantly and the irritation is irritating. do i need surgery or am i paranoid? i grew up with a sensitive stomach but it went away years ago now i just want to know if there's anything i can do to fit in with everyone else it might help to know i am on meds for bipolar and blood pressure and take the vitamin melatonin for sleep. the blood pressure meds aren't for there purpose they help with nightmares or something i don't know i have low blood pressure more then they like to say i take it at home on my own blood pressure machine oh i'm 27 6'3" weigh 230lbs and have pop more then a few glasses a day that's what i meant by sugar i drink light pop so i don't burp as much the coloring in cola makes me burp. please help me its not just burps i have well they other way and its bad
