3days Ago I Had Frequent Diarrhoea For 2 Hours In

3days ago I had frequent diarrhoea for 2 hours in the night. I had a small chicken pizza for my evening meal. I do have a small area of diverticulitis, and, as on previous occasions, I get severe pain in this area, then diarrhoea. My stool is now a normal consistency, but a sort of khaki colour. This happened a few years ago, and after a couple of days everything returned to normal . My bowel action is regular, no constipation, with normal stool.
