Doctor, 3 days back, I had little bit of outside food and from that night am getting crushing pain in upper stomach now and then which is leading to urge to pass loose stool with white mucus discharge. Sometimes, while lying down, it pains and leads to Smelly farts. In the last 1 month, am observing sensitivity to having outside food or spicy food and stomach getting upset immediately. Kindly advise if I should take medication to control the crushing upper stomach pain and loose Stool.
