I've just spoken to my pod surgeon and he said I have had rsd well over 2 years. Like you I haven't been treated for it. I just saw PM for the first time last week. He did tell me that if you have rsd for under 2 years than nerve blocks may work. if you have had it over 3 years, he told me that blocks don't work. He said if he did it, he would just be taking my money. He said anything over two years that spinal stims would be the treatment of choice. As you have had it over 3 years, that might explain why the block didn't work. I had my pod surgeon think rsd, then my new primary a couple of months ago, and now the PM said rsd. Idon't think there is a real blood test to prove it, but it does help to remove other possiblities. I wish the meds would help with my typing tho lol
