I find that when I can concentrate very hard on something, say a piece of writing or a game (I love Patience, or Solitaire if you like) or a computer problem (I'm a bit of a techie, or think I am) the pain goes into the background for a while.

Otherwise I'm in the very early stages of developing a home-brewed and somewhat vague theory, or perhaps philosophy to help me cope. It goes something like this: Our natural instinct is to try to run away from, or defeat, pain. So because I can't do either, I need to relearn and re-form my instinctive attitudes to this pain. That's about it (I said it was early stage), except that by some sort of logic or nonlogic, I give myself full permission to moan whenever, and others full permission to totally ignore my moans. They can be trained as well!

Addictions? Those are allowed too, but I'm not telling (except Patience, of course) .
