Wildberry,
Welcome to this site. I'm also from MN. I think that you need to be seen at a Pain Clinic, that will do a block which will help in th dx of RSD. I've been seeing the same Dr since 1998. If it wasn't for my Physical Therapist, I don't know how long it would have been before I was dx. I've also been seeing a Psychologist for my depression. If you're interested in getting the names of my Drs, please let me know and I'll definitely get them for you.
I know that I wouldn't be here today without the help that I've received, from my team of Drs. I wish you the best of luck in getting a proper dx and hope that you start getting some pain relief.
Gentle Hugs
