Doctors originally thought my RSD was due to a drill drop with puncture wound on my right foot. But after seeing some of the newer research I am wondering if the invasive treatment I had could actually have been the inciting incident. The foot hurt some but appeared to be healing, but doctors were concerned about infection and began treating with daily irrigation done with a local block of lidocaine/marcaine shots. The fifth irrigation treatment hurt way more than the ones prior and within an hour my ankle and then my whole leg up to the knee began to swell, redden, and feel hot. This seemed to be the onset of RSD as it was so dramatic. Is there any research as to how quickly RSD appears after the 'inciting' incident? What have other patients experienced?
