Yes, I use autohypnotic techniques for pain management.

I learned them many years ago while in art school (after my professional training)... to help me with imagery problems.

I didn't know at the time, but the same techniques also help
with pain management. I also do breathing exercises when I have my GI pain (this is a congenital defect I've had all my life), and the breathing also helps with PN pain.
(Take a deep breath, hold for a count of 8 (if you can't do that do what you can), then slowly let it out. This helps with the attendant anxiety that comes with pain.

The net is full of interesting ways to dissociate pain...this is one example I've tried, with some success:

Much of chronic pain research today is focusing on central (in the brain) management of pain perception. It is felt that this is a learned response, and can be to some extent "unlearned".

So yes, I do think meditation, or whatever other technique you use that is similar may be helpful. It is a good skill, in general for other issues in our lives as well.
