Well--isn't that an introduction?
It seems they went from zero to sixty with you over night? If you do an Internet search with RSD and Hooshmand, you'll find a good site by one of the former experts in the field. There's so much detailed info under the puzzles.
I've had RSD for 10 years. I have not tried the SCS yet. It seems a major gamble. You might see major improvement, but it might cause spread as well. A very tough call.
You're still in the window that is considered ideal to go into remission... I'd research Ketamine--outpatient treatment and inpatient. Look at Dr. Hooshmand's 4 F's diet. Research HBOT. Therapy in warm water. Etc.
Welcome to NT. If you Post your story in the RSD section as well, I'm sure you'll get lots of helpful info!
