My 11 yr old daughter has a red bumpy rash on her bottom lip and under the lip. She just has one large bump in the middle of the bottom lip and several small bumps above her chin. She originally thought it was just blemishes so she washed her face several times a day, but there was no improvement, and now they are red, very sore, & covered in a yellow/brown crust. They also burn if she touches or picks at them. I'm not sure what to do to get rid of them or what kind of medicine to put on them. I'm not even sure what is causing it.
