Hallow Dear,
The description of your symptoms and the discharge suggests that you are suffering from
fungal infection of vagina. You can get it confirmed by the examination of the discharge from the laboratory. This discharge also causes intense itching. The pain you are getting is due to the inflammation of vagina. Anti-fungal vaginal pessaries like
candid will help you to cure this. This infection is most of the times sexually transmitted. However, in sexually inactive girls, commode use also is known to cause this infection.
May be you could be having trichomonal infestation which can be treated by Metronidazol.
If you are sexually active woman, both of you will have to get the treatment simultaneously lest the risk of reinfections. Both of you should follow the following instructions apart from the medicinal treatment:
1. Till both of you are declared completely cured, observe sexual abstinence.

3. Daily boil the underwear.
4. Use panty liner (for woman).

Please report to the Gynaecologist for precise diagnosis and appropriate treatment.
I am sure this clarifies your doubts.
