about 3 months ago I had found a small lump under the skin of the labia majora , at it painless, and very hard. 3 days ago, My husband noticed 4 more lumps along the labia - same side, same description - small, incredibly hard, and painless. I am 35, and have had 5 vaginal births, no history of STD s, and have no idea what the lumps are. Any clues would be appreciated
