I have a problem when I eat-- Some times i look like I swallowed a basketball and I burp a lot. Then I feel like i have a rock in my stomach. Dr. said it could be gastroparesis. The stomach isnt emptying by squeezing the food out and it must empty by gravity. I have to go for tests . I also just had my gallbladder out and seem to be better so maybe that was the problem. Good Luck.
