How can i tell if i have vulvodynia or yeast infection? (my vulva and vagina itch every 3 hours or so during the day, not while im sleeping)

Vaginal itch: Vaginal itching without discharge can indicate infections like yeast or stis like herpes. It can indicate an allergic reaction to household products like certain soaps and laundry detergents. There are also some skin conditions liked lichen sclerosis which can cause vaginal itching. Start with an over the counter yeast cream. If not improving schedule a visit.
