I woke up with what felt like a raw blister on the back of my ear. I then noticed there were two small white bubbles, like bite marks. I took a shower and scrubbed the back of my ear. From then on it started oozing clear liquid continuously. I put a blister band aid on it and some leaked out and got on my hair as I slept. The stuff on my hair was whitish yellow and stringy. It has been like this for the past three days. Now the back of my ear is all crusty.
