This is a stunning article on the experience of pain. Its so excellently written; it really gets inside what that experience is like for this person.
For me, what is especially interesting is the description of becoming completely disembodied, out-of-body. I would love to give sessions to this person and see what happens if I teach them to manage to keep attention in the body even when this huge pain is there. So often, in all my experience working and seeing my teachers working, putting the attention there, instead of leaving the body or fighting the pain, is exactly the thing that helps the pain start to shift. It seems that an incredibly strong part of chronic, long-lasting pain is actually our fixed response to it, like clenching up against it, even if we’re doing that clenching totally unconsciously. It’s an amazing thing when someone with this kind of chronic pain experiences it changing and leaving.
