I'm having vaginal discharge and itching for past few months.. once I visited gynecologist and was told I'm having ringworm infection..cured after taking medicines. I'm not sexually active..Unmarried ...And only had sex once in my entire life...(at the beginning of this year) Then after my next period vaginal discharge increased..It is light yellow or white thick discharge.. or even little greenish...Itching was reduced by applying candid b lotion... But discharge is not going .It is having a bad smell like sour smell...No itching nor pain....
