Glad to have you on the forums! There are certainly a lot of people here with a real understanding of the issues you have mentioned. I know I've spent the last four and a half years researching pain and the psychology of pain. I'm sure you'll learn a lot if you want to.
Just feel free to jump in and post on any post that interests you, and don't be shy about starting threads or asking questions. That's what everyone's here for! Good luck, and I hope to see you posting here often!
