Hi, I had been having major problems with my stomach for the last 6 weeks, (pain in upper stomach, burning sensation which also went into my back, I do a lot of belching) I finally went to the county hospital in chicago, which I found out had the best doctors, plus they give you a complete body scan before sending you home. They told me I had gastritis, recommended maalox or mylanta and they prescribed ranitidine. They said the lining in my stomach was gone (which is from the pop I drink) and I have to be put on a diet (no pop, spicy food, chocolate, fried food) in order to restore lining in stomach. It will hurt a while until it is back to normal.
I hope this help you a little.
