diverticulitis
"I went to the doctor for simple gas pains. bladder was checked and bowels were checked. No blood was found. Was sent for an immediate bloodtest which showed signs of infection. was prescribed cipro and flagyl and was sent for barium for ct scan of the abdomen the next morning. 

The barium produced severe diarrhea but ct showed acute inflammation of the colon.

I took the cipro and flagyl and was nauseated and had diarrhea for 7 days. I finished the flagyl but had 3 more days of cipro to go. On the 8th day the nausea and weakness was so bad along with back pain and joint pain. I couldn't take it any more, so I quit the cipro 2 days early.

24 hours later I resumed my multivitamins and simvistatin and had a little diarrhea but has stopped now."
