BAD pubic area pain

I’ve been having persistent issues with my pubic area. On the dry area right before the “split” above the clitoris . I have had persistent itch/pain almost like there’s a healing sore there but there isn’t one & never have been one. I’ve been tested for STDs and infections. My OBGYN wants to do a biopsy to where they scrap an area of skin off to see if they can find the issue. It sounds so scary to me. Has anyone dealt with this before?
