Really odd sore/bump on my outter vaginal skin, too imbarressed to talk to my mom.

Hi there! This could be a sebaceous cyst. Sebaceous cysts most often disappear on their own and are not dangerous. Occasionally, they may become inflamed and tender. Sometimes sebaceous cysts grow large that they may interfere with your everyday life. When this happens, surgical removal may be necessary. Small inflamed cysts can often be treated by injection of steroid medications or with antibiotics.

thank you for replying. i feel less worried now that i might have an idea of what it is. so again thank you so much. :-)

It could also be from chafing do you exercise a lot?
