I had knee surgery that resulted in a cold foot and sensitivity to temperature change as a child, which continues to this day. There was seemingly an abnormal amount of pain in the knee for about 8-10 years. No pain in the foot accept that caused by the cold. Some atrophy to my calf and foot, that still exists. I went through nerve testing at the time and was given the option of meds or spinal surgery, both of which I declined.

Fast forward nearly 20 years, and after a couple hand surgeries, I developed RSD.

I've discussed my history with several docs. The consensus seems to be that perhaps I had a predisposition to the syndrome.

If you require surgery in the future, requesting a block right before hand would be a good idea. Avoid elective surgery at all costs. If you can avoid using ice, that's probably a good idea. If you begin experiencing burning pain in any area of your body, treat it like an emergency...and so long as you remain pain free, count your blessings.
