Hi everyone. Last night before going to bed I had a couple of episodes of diarrhea. Not a whole lot, but enough that my stomach started to kind of hurt. Then later on at night I woke up early and had pretty crazy muscle aches, and a slight fever (which I still have - fluctuates between about 99.5 and 100.2) I still have a little bit of diarrhea, maybe like 3 times today so far. I've had stomach issues before, but usually not with the aches and the fever. I'm worried that this could be something more serious, such as Crohn's. Would Crohn's aches and fever come on that quickly? I'm a 25 year old male that has had some stomach issues in the past. Mainly just loose stools every so often, usually around stressful times. But this seems different especially with the fever and aches. What else could it be? How worried should I be?
