Reverse self-injury 

Reverse self-injury is the act of using self-injury, to reach out to another self-injurer and show them how much they are hurting themselves and others.

I am a cutter, when my best friend caught me. He used reverse self-injury, he took my razor and cut himself for every new cut i had did. It was crazy but now i feel how he felt when i cut myself.

Joint Injury 

Occurs when two injuries come together to form a coalition.

Person #1: What's wrong with your arm?
Person #2: I don't know, but it hurts really bad.
Person #1: Where does it hurt?
Person #2: Can't tell if it's my elbow and/or my wrist.

Person #1: Sounds like a joint injury. You should get that looked at.
Person #2: Yeah that's probably a good idea.
