Is there a particular professional that could help me, do you know what it is or what could help me. Thank you

Hi, since I'm about 16 sometimes I get little lesions that bleed between my labia minora and vagina, I went to my doctor, a gynecologist and it was the dermatologist that told me I had dermatitis so I started taking the pill (mirvala) to balance my hormones. Recently I have had larger lesions and hot spots, I have been tested for all itss and for vph, but it is neither. That problem is gone, but the lesions still come back sometimes and for the last 1-2 days I've had a kind of pimple, but it's not bulging with white inside and it's uncomfortable but not itchy. I also use Lidodan 2% cream to freeze my lesions so it doesn't hurt. My lifestyle or habits have not changed, I eat pretty well and I take my pill continuously, I am in my period about 2-3 times a year.
