I noticed the other day that on the inside of my outer labia, there’s a weird lump. It seems to be on the surface, almost like a pimple but it’s hard and a brown, almost black colour. I tried squeezing it (probably not advisable lol) but it won’t pop and nothing comes out of it so I’ve ruled out an infected hair follicle, plus it’s not somewhere I would shave/wax. It’s not painful and I only know it’s there because I felt it purely by chance. I suffer quite badly with health anxiety so I’m trying to remain positive that it’s not something fatal! Any ideas what it might be?
