So basically Saturday night I had my friends come over to have a sleepover but one of my friends had this red bump on her waterline. We didn’t think nothing of it so they slept on the sofa and I slept in my room mind you my room is across the house, so like the sofa is by my room kind of but anyways we went to sleep, and when I woke up, I had the same thing that one of my friends had, which is a red bump on my waterline it, it hurts to blink and even close my eyes. Does anybody know what this is or how to cure it?
