Hello, I m very worried to what I think is an ingrown hair on my outer lip of my vagina. I went to my gp about 4 months ago, as it was quite big and she said it had turned into a cyst, and should go down. It did, but it has come back again suddenly over night and is the size of a hazel nut! Its very tender to touch, it hurts to walk, and has gone purple in colour. I m scared that its gone infected, and i cant see the hair. Will it need to be cut out?
