Little worried, itchy spot on vag lips

So a little while after my last period I began experiencing some itching on the inside of the right side lip of my vagina, close to the opening but not around it.

I used boric acid suppositories and the itch would go away, and then come back a few days later. Did this twice.

The itch mainly happens at night.

Well last night was awful, I didn’t scratch at all but put in a suppository this morning because i figured this was a sign of a yeast infection

Well it’s bothering me today so I just took a mirror and checked and there’s a red patch on the inside of the lip of my vagina on the right side. I’ve never seen anything like it before so I have no idea what it is. But it’s causing the itch. An itch is all I’ve been experiencing. It’s not constant, but when it happens at night it dosent go away.

I can’t afford to go to a doctor but if needed I’ll probably make a planned parenthood appointment.

This just happened randomly.

I’ve been with the same person for almost 2 years now so I’m clueless as to what this is or what caused it.
