We reported three cases of RSD treated with difficulty. In the first case, occurred after stripping of the lower leg varix. In the second case, it occurred after arthroscopy of the knee. In the second case, it occurred after sciatica. All three cases were treated by the sympathetic blockade. Their periods from the onset to the start of the sympathetic blockade were about nine months, five months and six months respectively. The long period was thought to be the most major cause of difficulty in treatment.
