The symptoms as mentioned in your post suggest that you might be having Urinary Tract Infection
Though Nitrite is negative, presence of leukocytes
in the urine indicates undergoing infection/inflammatory process.
The treatment involves:
1. Drinking lots of water (it dilutes the urine & reduces the burning sensation)
2. Antibiotics depending upon culture & sensitivity reports.
3. If there is associated fever
, then paracetamol
500 mg three times in a day can be added.
Sometimes, UTI may persist due to inappropriate dosage of medications & inadequate duration of treatment.
So, it will be better to consult an Urologist
with the reports of your Urine analysis.
One more thing...avoid acidic foods, carbonated drinks and alcohol...& maintain good hygiene.
There is no need to worry...you will be fine.
Wishing you a speedy recovery.
Thanks & take care.
