I am familiar with CRPS. It's a challenge. I hope you get some relief. I am on a facebook support group site for the weird sarcoma that I am treated for. I understand your being tired of the religious groups. I avoid the "I'll pray for you" posts, which are numerous, and try to stick to strategies to manage the illness. Sometimes I have to take a break from the online group, when there is too much religion there.
Anyway, welcome and I hope you enjoy Atheist Nexus.
