Suggest Treatment For A Bump On The Labia Majora

Hi, I have a bump on my labia majora. It isn t red nor is it visible to the eye. If you touch the area where it s located, you can feel a hard bump. It doesn t hurt. What do you think it may be? I have a history of irregular menstruation and I also have another bump, which feels similar to the one I just described, on the back of my neck.
