For those of you not familiar with the female anatomy, the labia majora are the external folds of skin surrounding the urinary and vaginal openings. Your rash or bump could be a common dermatitis or skin irritation from tight clothing or the type of soap you might be using. Many bumps that occur in the labia majora are known as sebaceous cysts. They result when oily material blocks a sebaceous duct or gland in the skin. Sebaceous cyst are benign and usually ignored unless they become infected or painful. These cysts may disappear spontaneously or remain in place without causing any problems.
Other causes of bumps in the genital area are human papilloma virus which cause genital warts and other infections that may be sexually transmitted.
All this said, the only way for sure to know what the bumps are, and get any treatment, is to be examined by a doctor. Seeing a doctor will give you a definitive diagnosis and help relieve your anxiety. Once your doctor has identified the problem, he/she can prescribe a course of treatment if necessary. You should also get in the habit of having regular checkups with your physician. Adolescence is a time of tremendous change and good medical care should be part of it.
