Is it normal to get diarrhea and severe cramping at the same time then when its over constipation?

Can be: Acute episode could cause the cramping and diarrhea. Then "cleaned out" so no bm for a while. If associated fever, nausea, bleeding, ongoing symptoms need to see md.

Yes: I hope i understand the question right, but there is a phenomenon in severe constipation, especially in children, where one is so constipated there is a ball of stool in the rectum. This causes a circumstance where looser stool from behind can slide out causing diarrhea and " accidents". Obviously there can also be cramps and discomfort.
