You are right. CRPS does spread. Cymbalta was bad for me and lyrica same as gabatine (sp) no help.
Sadly we need the gp and burning bridges can hurt you more than them. Believe me, I understand and you are not WRONG. Some are just rude! But they hold the references that can lead you in the right direction. Please continue to be a squeeky wheel. Eventually you will be greased.
Vent your heart out here. We are in the same boat. Some more further along but still fighting.
