Strange lump on vulva (no pics)


Y’all idk what this is. It showed up about two days ago and is tender to the touch. It’s a lump under my skin on my labia majora (outer lips). It’s about the size of my pinky finger, red, and tender to touch. Everything I’m reading about cysts are all on the labia minora, and I’m pretty sure it’s too big to be just an ingrown hair. I’m also having a lot of excess white discharge. Not sure if that’s related or not. Anyone have any ideas?
