Hi, I am a bit embarrassed, but I have a hard bump on my mons pubis. I got them in the past year, everytime I have sleep deprivation. It s very hard and painful and can be between half a centimeter and a centimeter and a half. They appear on different parts of the mons pubis, but now I have one on my labia majora as well. What is it and should I be worried? The bump feels rather hard too, like a painful bump on your head after accidentally hitting something.
