Hi and welcome to HCM- Thank you for your question.
This is usually self limiting and may not indicate any disorder however, in some cases urinary or
std may be present if this last for more days.
I will suggest you keep the private parts clean and dry. Use of Lactic acid containing vaginal wash at Bath time is advisable. Use of Condom, over the period of next 2 weeks while having sexual activity is advisable.
I STD tests is done then in case of positivity you can have a week long course of Doxycycline 100 mg. orally twice a for a week. Antifungal agents like
Fluconazole 150 mg once a week.
A local ointment containing
clotrimazole and
clindamycin twice daily for a week to be applied on the private parts and
vaginal tablets of Clotrimazole and Clindamycin at night for 7days.
Please seek prescription help from your treating gynecologist for getting oral, local and vaginal antibacterial and antifungal agents.
I hope this answer helps you. Wish you good health. Regards
