For about a week and a half now every time I eat anything I have stomach pain shortly after, followed by digestive pain that almost feels like constipation but then it’s followed by watery diarrhea. It seems like it has got progressively worse over the week and a half. I have tried eating very small meals and I drink lots of water but still have yet to have a solid bowel movement over this time span. It’s beginning to become a problem as I’ve been eating way less then I normally would as the light hunger pain is easier to deal with then the pain of digestion. I thought it was just a stomach flu or bug but I would have gotten over it by now if that was the case?
Maybe try a food diary to see if a food has upset your stomach. Try eating bland foods and avoid anything spicy, rich or fatty. Cook from fresh and avoid anything processed. Have you eaten anything unusual?
What does the pain feel like? Is it in one location or is it generalised and does it move about? I would see your doctor if nothing improves after a week.
If it came on suddenly for the first time, or even not for the first time but after a long period of stability then it may be a bug which can take up to 2 plus weeks to resolve. Has anything changes in what you eat, your emotional state etc If it does not resolve and nothing changed to bring it on then ask your doctor to check your stool for Infection
