Hi Empty,
RSD pain was first 'discovered' and dx'd during the Civil War because of the burning nerve pain complained about by........amputees !
Like amputees with phantom limb pain, our nerves are misfiring and not reading the body's signals correctly.
Performing surgery to deliberatey cut more nerves in the hope it will fix the nervous system in someone that we already know has a screwed up nervous system seems foolhardy, at best.
You have my sympathies.......I can't imagine how much worse it is to deal with RSD as a young adult. Although at 45, I'm not quite dead yet

, I am grateful that I got to enjoy high school and sports, college and partying, being physically active in my career of nursing, falling in love, getting married, and having kids..before my world fell apart with RSD.
It seems like fighting for Ketamine might be a good place to start.
