As per your information, you are probably suffering from vaginal infection
by using common toilet. I suggest you to proceed vaginal examination and swab test (to detect causative agent) for proper treatment.
You may need to take vaginal suppository capsule like CLINGEN FORTE for 5-7 days. Maintain genital hygiene properly.
Consult with your gynecologist for clinical examination and need some tests including STD
profile & urine examination.
Avoid chemical bath products and drink plenty of fluids.
Be well and take care.
