I will say from personal experience, and it's probably too personal, but I have had a few on the outer labia. They aren't like the others....they've always been just like you said. "Knots". I would find a doctor and make sure that's what it is. Just to be on the safe side.
And don't give up on the Doctor hunt. I had said before I go to the a Nurse. She's also a midwife. And she's done what no other doctor I've ever seen has...she figured out what was wrong with me! So maybe that's an idea for you?
Good Luck and I wouldn't worry to much about the knot, it should go away on its own. I know it's hard not to think about cuz it's painful and embarrassing. But it's not overally unusual ya know?
And as far as helping with the pain..I don't know what to tell ya. The only thing I've ever found that works on stopping them from coming so much is, believe it or not...skin bleach. The stuff most people use for sun spots or freckles. But I don't think I'd use it where you have it. I do know that I've been on my meds for about a week and a half and they aren't as bad as they were...don't know if its connected, but Lord I hope so.
