I just had a cystoscopy of my bladder. The results came back no infection. Trace blood. And way to many white blood cells to count. Trace blood has been showing up in my urine over the years and I have had many UTIS. I Alsoo have MS.The caustically showed so mush inflammation in the bladder it was to hard to read. My doctor put me on antibiotics to help calm down the sever inflammation and swelling and has me coming back in another three weeks to do another scope.
