Mine started in my left ankle. Then after a lumbar sympathetic block is spread to my back, then up my neck, then shoulders, then down my arms into my hands, and around my front into my torso. Then...later...after getting bumped on my left hip the pain spread there and gradually down that leg until now my whole left leg is in pain. After I had a C Section to have my daughter in 2014...I now also have severe pain in my abdomen. That leaves my right leg and my head above the neck without CRPS. Sort of hopped all over but there was always trauma that started the spread.
