My husband constantly has diarrhea and stomach pains shortly after eatting. Doctors say to watch what he eats, but foods may not bother him one day but even if cooked exactly the same way another day, it may upset his stomach. He is always in the bathroom and always in pain. He is a wonderful man and I hate to see him in pain all of the time. He even has to work (driving tractor trailer like this). Can you please give me advice?
