I eat meat regularly, but rarely eat steak. The other day I had steak for dinner and later that night it felt like there was a knot in my stomach, then finally had a large bowel movement and felt like a million bucks. The next day I had the leftovers and later that night the cramping came back and has lasted 2 days so far. I keep feeling like I have to have another large bowel movement but am only able to get rid of a few pebble-sized feces. My wife who had the same dinner is fine. What can I do to alleviate this?
