Have a tingling feeling that seems like it s inside my urethra. I m a 37 y/o single female. I have not been sexually active in 2yrs... I do have a hx of UTI s, & kidney stones. I was last treated for a UTI 8/2014. However-- I don t have any of the common s/s that is typically associated w/ previous UTI s.. i.e.- frequent/urgent feeling to urinate, blood in urine, ammonia strong smell of urine... I never have the burning sensation that is typically associated with UTI s, & that others complain about. The tingling sensation that I m currently experiencing in my urethra, I don t recall ever having w/ previous UTI s.. It also seems to get worse at night-- or should I say, I m more aware of it at night? What could this be? Another UTI manifesting itself w/ a new symptom for me? Should I be concerned? Any analysis on this prognosis would be greatly appreciated!
