It would seem that no matter what I eat or do not eat, by the end of most days my stomach is gurgling and growling. I know then what is coming, several hours of a bloated abdomin and feeling as if I am full of gas and unable to pass it. I drink a glass of baking soda with water and it gives little relief. I have tried rolaids, other antacids and nothings can stop it or seems to prevent it. I have tried staying off dairy, no starch, I dont eat fried foods. I am completely miserable and in agony several hours each night. The pain is all in my upper abdomin and when I lay down on my back on the floor and feel my abdomin, the upper left side is very tender to the touch. Help me what could it be.
