Thanks for your question on Healthcare Magic.
I can understand your concern.
Burning on vagina is the first sign of
vaginal infection.
So in my opinion, we should rule out infection first.
So consult gynecologist and get done clinical examination of vagina and microscopic examination of vaginal scrappings.
This will identify the causative organism.
You will need antibiotic and anti inflammatory drugs.
Drink plenty of fluids orally and keep your self hydrated. Wear cotton undergarments only.
Avoid
masturbation or sex sexual intercourse for few days if you are sexually active.
Avoid moisture and perspiration in private parts. Keep proper hygiene of private part.
Don't worry, you will be alright with all these.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
