question: I have a small light brown blister on the top right side of my lower lip that I woke up with this morning.  It's approximately one quarter mm in diameter, it's getting sticky and some brown pus is coming out of it at a very slow rate.  My lips are kind of dry so I used Chapstick Moisturizer on them after noticing it.  I'm not sure if this is something to be concerned about or not.  I don't think I have the HSV-1 Virus and haven't kissed a girl for around 2.5 years.  I can send a picture if that would help.  Thanks!
