Please help!!

Hey guys, so recently I’ve been having a problem with getting cysts near my vagina. It’s not on inside or on the labia but it’s kinda on the cheek, closer to my anal, if that makes sense. I don’t understand why I’m getting them, I’ve looked it up online and I haven’t found what I have. There’s like two that go away and come back and it causes pretty bad pain. It hurts to walk, sit, wear jeans. They usually come about every 2 weeks and only last for like 3-7 days. Please suggest what I should do or comment if you know what I have. Sorry if this is kinda graphic. Thank you.
