RSD is a strange condition in that some procedures work for some not others. Catch 22 also fits this disease in so many ways. My wife made up her mind years ago (after doing extensive reading on RSD) to avoid evasive procedures. She did except physical therapy and ketamine infusions. She avoided surgeries, blocks etc.. Her thinking is the disease will spread most likely so let it take its course without speeding the process up with temporary fixes. There is a logic in this thinking, but I'm sure for others it's not. Many doctors did not like my wife's thinking on this and disregarded her as having the pain in her mind instead, even though she showed most physical symptoms of RSD and a severely crippled right arm and hand. By not allowing doctors in the early stage of her RSD to poke and prod, cut and stick etc. my dear wife was severely neglected by doctors. However, over time the disease has spread but I think she may have been worse off if evasive treatments took place.
