Return of urinary tract infection or spinal problem?

Well I need an urgent response, some 3 years ago I had infection in the urine that hit my right kidney inflamed, had pus and lost blood through the urine, the doctor passed some medicines I took and passed, later he asked me to do the same tests only now after 3 years I did on the ultrasound and blood was normal, there was only one change in the urine that gave 8 to 10 red cells per field wanted to know if it is a kidney problem? One day I've been suffering pains below the right rib is a little higher than the left is not a strong pain, but it bothers the times when breathing hurts and is more frequent at night is it my old problem or is it a column?
Expert answer:

The urine infection you have had in the past and been cured does not come back any more, it may have other infections, but it is not the same. Another urinary infection may even be but, there are many symptoms missing to complete the picture. Column problem, maybe, but the pain region does not hit the pain in the spine.
