Hello dear Understand your concern Vaginal itching and frequent urination in sexual active women mainly due to vaginal infection. Most common looks like bacterial vaginosis and candidiasis. Other possibility is urinary tract infection. In my practice first I advice following investigations: Vaginal swab tests to confirm the infections. Bacterial vaginosis should be treated by metronidazole Candidiasis should be treated by flucanazole ointment or by oral durg. Urine routine, microscopic and culture to diagnose UTI: It should be treated by specific antibiotic, nitrozolium and syrup cidal. Other advice: Drink plenty of waters, wash vagina with warm salted waters and use V-Vginal plus wash, apply apple cidar vinegar and wear pure cotton loose under garments, if itching is severe can be reduce by mild hyrocortisone ointment. Hope this may help you Best regards Dr. Sagar
