Does anyone else do this? Ive hAd chronic pain for as long as I can remember, which has gotten increasingly worse for the last 2 years or so. I also bite my fingers. Not my nails, but the skin around them. They are bloody, raw, look horrible, and really sting whenever I have to do something. But I can't stop! and I'm wondering if it's linked to my pain, and acting as a sort of 'distraction pain'. Or am i just crazy?! anyone else do anything like this?
