What do I think of the little tears? I think, talk to your doc about this all. Tell her if you're having sex, and whether the sex has all been with only one partner, and whether the partner wears a condom, and what type of condom, and if you use lube or vaginal cream. Point out your history of vestibulodynia, and tell if that coincides with a time period when you had regular sex with a partner, and whether you masturbate and what you use to do so, and whether you regularly sterilize your "toy." Also, whether you've been taking any other kind of meds (like a steroid) or using any natural body creams of any type that have estrogenic effects, like wild yam cream. Also, whether you've changed detergents recently and if you've been wearing less absorbent underwear a lot, or perhaps wearing a thong. And get tested for all the STDs if you haven't since this all hit. There are just so many directions to go with this that your doctor is the one to advise you.
It might be BV, did she swab you for it? And possibly a yeast infection on top of it. In the meantime, you might try a sitzbath in a white vinegar solution.
