I have a white bump with no head on my labia minora and ive had it for at least a year, I have been checked for stds and never thought about asking my doctor what the bump was. a few years ago i had infection of the labia but it was on the inside of my body i tried popping the bump and it came out like a little string of hard white stuff and it came back bigger and now I have 2 white bumps and I have no idea what it is. I would go to the doctor but i have no health insurance at this time.
