Ed,
Welcome to the forum. Don't just visit, join.
Sorry about your condition. I notice the doc says he never SAW it spread. A lot of WC doctors will say that. But it does!
Keep in mind you have the right to a second opinion. Find a neurologist who has dealt with RSD and you'll find out it does.
Once your nerves get RSD it can spread anywhere.
Mine started in my left wrist/hand and has spread up my arm, left side of my neck and head and is now starting in my left foot/leg. You'll find most folks in here have some spreading going on.
If a doctor says RSD doesn't spread he/she is the wrong doctor...
