I use to be so healthy. I was doing arobics 30 minutes every day. Then I was in a car accident and had a leg injury. The E.R. did not give me any antibiotics while I was there, did not send me home with any, and they did not give me a tetnus shot. One month later that injury develped a life threatening infection. The new doctor saved my life by removing part of my calf. Then in that same site I developed RSD. A year after being diagnosed with RSD in my calf area, I fell on both knees. The RSD spread up my leg to my knee and up to my upper thigh. I developed RSD in the other knee as well. I have to have pain management or I do not walk, or I use a cane, or use a walked. My pain managemnt doctor does a good job of managing the pain most of the time. However, he does not know about RSD. My neurologist does not know much about RSD either. No one can tell me anything. I am weak in the knees and legs. I have fallen twice in one weak. I have no idea what to expect in the future. I take pain pills only when I have to as I do not want to be dependent on them. No one can tell me anything around here.
