I thought it was just constipation, but a trip to the ER and a CatScan later said it was diverticulitis. So, I spent three nights in the hospital being pumped full of antibiotics and fluids.
I whooshed everything out of my bowels the first night, several times. Then continued to spritz or tinkle every half hour it seemed for the next two days.
I am on the mend. Another couple days of low fiber diet then on to a high fiber one. Plus, drinking lots of water. Apparently this can happen if you don't dring enough water.
