Bullfrog,
I'm so sorry what your wife has to go through. You're both in my prayers. Does she have some kind of nerve damage (sorry if you posted about it b4 and I missed it).
My fiance has RSD, a nerve problem, he had three or four sets of shots in his back to block the nerve, no help, now the doc wants to implant a permanent stimulator thing (can't think of the name right now) but workers comp keeps denying it.
Hope everything turns out well for your wife, she is very lovely!
Thanks for keeping us posted.
