Hello, I'm here to ask about a swollen Labia Minora. It's quite embarrassing really however I believe I have to have help. I'm seventeen and have not been involved in sexual activity however like I said it's swollen and very painful. Also, there is a sore on the lower part. I'm not sure if this is an ulcer. Since I was a child I've been getting ulcers in my mouth and my mother believes this is the cause. Can you help?
