Ingrown hair or something worse?

I made a previous post and I wasn’t clear. IM NOT SHAVING THE INSIDE OF MY VAGINA. I’m talking about the area BEFORE the lips, but after the the area that is most heavy with hair. I randomly get a small sore bump a day or a few after shaving. But only so times does it contain puss. Most of the time it just blood. But it’s ALWAYS in the same exact spot. Is this an ingrown hair or worse? It’s only ever one
