For some reason today I woke up with pain in my intestinal area. I had pain in my head so I figured I was hungry so I ate some foods but everything I ate I would just throw it up. I kept feeling like a had to poop so I went to the bathroom but for some reason chunks of poop and yellow liquid came out of my anus. For some reason when I'm done using the bathroom and I wipe it feels like my anus is just burning every time I would wipe. The next day I woke up in the morning and I don't know but I think it was diarrhea in my pants and it was sinking through them and it was watery. Can someone please tell me what this might be.
