Thanks for the query to ATD,
The symptoms of vaginal and anal itchiness indicate a fungal infection. Ideally a swab culture should be done from both sites to grow and isolate fungal spores to confirm the diagnosis. Antifungal ointment like clotrimazole 1% cream can be applied locally over the vulva and also around the anus for 7 days. This should help providing relief.
Hope this helps.
