I never get infections or scars or anything, and it doesn't bother me if it gets filled up with blood or something, but I'm concerned.
I have a compulsion to fill in holes in my skin with ink
Hi Houston, The fact that you're concerned says a lot. If I was your therapist I'd ask you questions about your worries and how this is causing a problem in your life. You're causing perhaps permanent changes (damage?) to your body, and it's likely you're trying to express something...pain maybe? A therapist can help you to explore what's going on for you and how to get your needs for self-expression met in a more healthy way. Good luck!
