I Was Diagnosed With Diverticulitis By Ct San With Contrast

I was diagnosed with diverticulitis by ct san with contrast a week ago Thursday. I was given generic for Cipro and flagual. I don't have the lower abdomen pain anymore, but I have a burning pain on my upper left side along with the feeling that something is trying to "push" on the inside to the outside. I'm not sure if this is something I need to be very concerned about. I still have loose bowel movements a little while each time after I eat.
