Last night before bed my stomach was aching after a bowel movement. It felt like I hadn't finished properly. I woke up in the night with stomach pain. It felt like trapped gas. I had a hot bath and drank warm water. I ended up doing a normal bowel movement but the stomach pain was still there. Over the next 2 hours I had bouts of diarrhoa and still the trapped wind feeling. It hurts above and below my belly button and lower abdomen. I feel like I need to pass wind but can't. My stomach is still hurting now when pressed. I've had 3 more mushy stools. My stomach feels full of gas but it's not passing. Could this be IBS or could it be something worse? Even walking my stomach hurts. I've had IBS for years but never pain like this.
