I have pain on my left back on hip. Pain comes to my left foot. Pain is not continues, when it pains I feel wet on my panty. Dr said it is uti. Reason?

Not UTI. Back pain the left foot cannot be due to a simple uti. Back pain to the left foot is likely due to lumbosacral radiculpahty. The incontinence is likely from bladder dysfunction due to the same thing that's causing the back pain and radiculopathy and not uti. This could turn out to be a true medical emergency and suggest proper medical evaluation much sooner than later.
