No infection: Those test results prove you have no infection. Other conditions can cause UTI-like symptoms. Overactive bladder is most common, but the condition callsed intersticial cystitis is pretty common as well; and there's always the possibility of more serious conditions like urinary tract stones, cancer, etc. If you're not seeing a doctor, do it now. If you are but without success, see a urologist.
