This is a video of a large abscess being drained on an elbow joint and it will absolutely scar you for life!I couldn't watch the whole thing and it looks like a foot not an elbow.
Everybody has their thing that will just make you freak out. Some people hate bugs, I hate things like this! If this was happening in the same room I was in, I would probably flip out and kill everyone in the room. That's how freaked out I would get!
