I have been experiencing stomach issues, which my Rheumatologist feels is directly related to a medication I am taking. With that, I have changed my eating habits to much smaller meals and have tried to stay with foods that are easily digested. With that, I have eaten very little today (1 protein shake, 1/2 avocado, 1 slice whole wheat/grain bread, 2 small Campari tomatoes & water...that s it since 7am...currently almost 3pm. I am now having pains, as if I over ate. Can you tell me if what I can do and if you have any thoughts as to what my problem is?
