Hello, three days ago, I was feeling pain in my back, no burning or pain when urinating, but a fullness in the bladder. I went to the clinic and a urine sample was taken. The doctor stated that I had blood and pus present in my urine. He is treating me for a U.T.I. What concerns me is that I do not have pain or burning when urinating. I can't physically see blood in my urine. Well, it has been three days on Cipro and I really do not feel any better. My back is still achy and I feel nauseous and extremely tired. What are your thoughts? Thank you.
