Hi, I have CRPS type 2 in my Lt arm that spread to my right arm and upper body. Injections, blood draws and all caused a terrible feeling of broken glass beneath my skin on my right arm. Now I do my best to limit all needle pokes to my lower extremities. It's risky as it's possible to spread this to my feet but so far no problems and I don't have to deal with the intense flare ups caused by needle pokes anyway.
I hope you feel better soon and have family/friends to support
