I hesitate to add a link to this on the thread, but there is an interesting story around chronic pain actually being psychological and there are now some high quality studies coming out.

I especially hate to link to LessWrong but this is an actually decent thread on the topic:

I didn't know about any of this and had never been exposed to any of it when I drew my conclusions and started to feel less pain. Don't get me wrong, there are still things that will set my back off, but now I probably go actual years without even thinking about it.
