Is Itching a form of compulsion?

I have been going through the mental ringer and I've been trying to identify where my issues are coming from. I've had childhood trauma in the past and relationship trauma which have had an impact on my life. Now that I'm in an unpredictable spot in life, my control issues are heavily weighing on me. I've been trying to find the root of the control issues and the recent obsession I've picked up over a new person. I've never considered OCD before because I've never had the compulsions like most do. However many say that self harm is considered a compulsion. I've given up that habit because it's not a good habit, but lately I've noticed when I get stressed out really bad I itch myself like crazy. Could itching be a type of compulsion replacing the self harm?
