Hello and welcome to HCM,
A feeling of burning sensation in the vulval region after you urinate suggests an infection of the urinary tract
You need to get an urine examination- routine and microscopy.
These examination will identify any evidence of infection.
Once infection is identified, a culture and drug sensitivity can be done for correct institution of antibiotic.
Avoid sexual contact till the infection clears away as the infection can transmit to your partner.
Thanks and take care
Dr Shailja P Wahal
