Hi and thanks for the query,
Burning urination could be as a result of a urinary tract infection or an inflammation or infection at the level of the vulva. The fast or rapid urinalysis could not at times not show the presence of a urinary tract infection. A urine culture might be necessary at some point in time. However, it is very important that a good clinical evaluation be done to exclude a possible lesion at the level of the vulva and vagina that produce the pain when in contact with the urine. For now , drink a lot of water, book an appointment with your gynecologist for a urine culture and appropriate gynecologic examination.
thanks and best regards,

hi,
With the statement you have given you are having spotting after menstruation stopped.
Now you have associated burning micturition and burning sensation around vagina. Some test were done for UTI - result came as normal.
What you need now is a complete urine analysis including Culture and Sensitivity.
A gynecological examination to rule out infection like moniliasis. and clinical examination of your genital area including investigations if needed
UTi can be ascending or descending
Treatment take Plenty of water and mild diuretic, till results arrive
Best wishes

Hello and welcome to HCM.

Thank you for your query.

First of all, I do not doubt the laboratory you visited, but at times, an inexperienced laboratory technician can miss the crucial points that help in making a diagnosis, and thus, report a negative result. I request you to repeat the urine analysis or go for a more specific investigation like a urine culture and sensitivity examination at a more experienced and well-renowned laboratory. This will ensure accurate results.

Once this is done and if the report is still negative, going for a screening of sexually transmitted diseases will be another option, along with and abdominal and pelvic ultrasound, to rule out/diagnose other abnormalities of the renal system.

I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you.

Best wishes.
