Causes of loose yellow stools and severe cramping?

[foxmx30]

As you know I have been having severe cramping in my lower stomach. It started the other day when I ate an Italian restaurant. It didn't make me feel horrible but it definitely made me feel different and bloated. Later on that night, I made myself eat a sub from Subway. It just added to the full bloated feeling and i felt gassy throughout the whole night. Well now today, from about 3 am this morning, I have been suffering from the worst case of diarrhea ever. It's yellow and it's almost like water and its mucus like =/ I've tried to make myself eat crackers, I feel hungry, but it just goes through me like it's nothing. It doesn't hurt to eat, and the cramps come and go but my bottom is really starting to hurt from all my trips to the bathroom. I am only 22, I've been to the doctor before for similar symptoms but they weren't this severe. They told me it was IBS. I don't know if it is a flare up or if I have some sort of infection. Anyone else out there that has had this problem? Or have an idea what it is? Thanks.

Anytime you have diarrhea you need to keep the anal area coated with vaseline, so that it doesn't get itrritated.  I have IBS and have never had yellow stool, which can be an indication of other problems.  Keep yourself hydrated, and get to the doctor.
