I agree with what some of the others have said. While it may be MS, it is worth checking with your dr. You may have come down with a stomach bug or something or it could be stress.

I have neurogenic bowel and bladder issues related to MS. While I opted not to do the medication route as I am not bad enough, bowel issues are not fun. I can fluctuate some but rarely have diarrhea, I just get a little "loose." And, under stress, I am always loose.

I hope things are getting better for you.
