Skin tear - waxing injury

In Oct 2024, I was self-waxing and tore off a small piece of skin off the edge of my vagina at the opening (6 o'clock position). It still hurts, even though I've tried everything, including these doctor recommentations: avoided penetrative sex for last 6 months; used vaginal estradiol cream, Aquaphor or coconut oil on it to keep it moist; gently massaged the area of the tear recently; left it entirely alone with no topical ointments; etc. My partner and I are at our wits end. It feels like a wound that is irritated or sore. I know having sex will just make it worse. I don't know where to turn. Any ideas? I can post a photo of the original skin tear but it's a bit graphic.
