I Was Diagnosed With RSD In 1983 At Duke Hospital.

I was diagnosed with RSD in 1983 at Duke Hospital. Several years ago I had cellulitis . My head was the only thing I could move. After 4 mos in rehab I learned to walk all over again and was discharged. They led me to believe cellulitis was the cause of my limbs not moving. I now believe it triggered the RSD and that was why I could only move my head. Your opinion?
