I ve been experiencing severely watery diarrhea for about 4 hours now, but before that had loose stool and severe stomach cramps/pain. I was fine all day yesterday, went to bed and woke up around 5:30AM with the worst stomach pains ever, and uncontrollable burps that smelled of rotten eggs. I decided I would try using the restroom, it helped for about 5 minutes before the pain returned, bringing diarrhea with it. I took some pepto-bismol thinking it would help, and it did help the stomach pain, but the diarrhea got worse. I thought since my stomach stopped hurting and I hadn t had to go to the bathroom for 30 minutes it would be safe to go back to sleep. It s now completely watery and a light pink color. Is this any cause for concern?
