I don't know if there is an official definition of full-body. I have always thought I was "lucky" because the RSD seemed to be confined to my left leg and foot. As painful as it got, I had pretty good health/strength/pain levels everywhere else. This lasted for many years.

A couple of years ago, I started to get pain in my right leg, then my hands, then my shoulder. etc. Now, there are times when I hurt all over and any little trauma (like an injection or blood test) will cause a flare-up. I suppose that is what people refer to as full-body. It is almost a comparative thing.

I still have the worst pain in my left leg. I am not being treated any differently for the full-body, other than the SCS does nothing for any other areas.

I am still lucky because I have not had to quit my job (yet.) Good luck to you.
