I'm a 19 year old girl,and have recently discovered a blister on my labia majora,the skin fell off and its healing but just above it are little (and I do mean little) pimples/sores. They're quite painful and itchy sometimes and are all concentrated in one place. Looks like they're pus filled but I don't wanna pop them coz they're painful. I'm scared I might have Herpes or something, but I haven't had sex in over a month and these symptoms are recent. What is going on with me????
