Urethra burning without UTI symptoms.

I had diagnosed with UTI in this Dec  as I had a burning sensation in tip of the urethra which comes and goes in a day  for over several months before and finally thought of getting it checked. But not typically any other UTI symptoms. I am not a sexually active person as well No other discharges or colour differences in private areas. When the urine and blood test was done There were 25 pus cells detected in urine and few nitrates were detected and other vitals were in normal range for both urine and blood sample. Creatinine was also in a normal range During urine culture Klebsiella pneumoniae bacteria was detected. Following which the urologist gave me Taxim- o for 7 days with citralka solution . I was feeling better when I was having the combination of both . I did not feel any burning sensation on those days Now it's almost 1 week since the meds have stopped , now I am feeling that my urethral area is getting heated / warm often in a day What should I do ? In this case
