Call the doctor. I don't have experience with B12 shots, but in my two years of CD I've learned that diarrhea can get out of control really fast. When I flare (brought on by salmonella once and c. diff. three times), I can go from normal BMs to 20+ very bloody, liquid BMs per day within a week. This last time I went from almost constipation from IV dilaudid in the hospital for pancreatitis to the bleeding and cramping in less than 48 hours. This is a bit extreme, most don't have it happen that fast I don't think, but you just need to be careful because dehydration can happen so fast.
