So this is the 3rd time this has happened to me! I get this thing that fills like a ball on my Libia minora! For days it will get irritated and get bigger. At some point it will bust and blood and puss comes out! I've been recently checked (pap) and blood test for stds and all came back ok so I know it's nothing like that! Has anyone else had this happened or what can cause this! It gets painful to were I can't sit,walk ,or stand certain ways
