Thanks for using Healthcaremagic.
After going through your history you had suffered Vertigo
and now it has improved with time and the medicine you was using.
You should take antibiotic for Urinary Tract infection
as it can occur without symptoms.
Please do not go by advice of chemist and follow instructions of your doctor.
Later on repeat urine analysis to confirm that it has cleared the pus cells from urine as without symptoms there can be damage to kidneys so do investigate to confirm it.
The organism in Urinary tract are sometime resistant to commonly used drugs and need to do a culture and sensitivity.
If necessary a Ultrasonography
of abdomen will help to know condition of kidneys.
