I'm so sorry to hear you are in so much pain. I was also involved in a push through the pain program, it ended up making my pain worse and the CRPS spread. To me they just don't have validity and are run by people who must think CRPS is primarily in your head. It also produced a lot of "I'm failing" feelings for me. When I started working with a PT that got it, we only pushed to the "hurts a lot" and then backed off, brought the pain down and then tried again. This worked tremendously for me.
I also believe being on the right meds is important. LDN was a game changer for me as well and Ketamine Infusions. I know this is easier said than done, especially when there are issues with insurance.
Good luck and many healing vibes sent your way
