I have been told I have blood in my urine, (called dr., at 10 am, have not returned my call yet) I just started very mild/faint pain in lower back, above waist on left side. I am also recovering, slowly, from a diverticulitis attack, treated by Cypro & flagel, which was diagnosed by my physician at my yearly physical last Thursday. As this is my 3rd experience with diverticulitis, no CT was done., thanks
