Hi Amila Pradeep
Welcome to HealthcareMagic.
I guess You have urinary infection even now .Burning sensation while passing urine is a symptom of urinary infection.It is very frequent in women.
I advise you to visit your Gynecologist and get examined.She may advise you a course of antibiotic which is very essential to treat infection quickly.
Meanwhile , You should take adequate water (5-6 liters/day ) .Intake of fluids should be increased.Please maintain proper hygiene with your clothes and also partner.
You should get this treated properly , as chronic urinary infection can have effect on your kidney
s and also your baby `s weight in pregnancy
Hope I answered your question.
