                        I'll trade you knees. I have RSD in my left knee.  I've been through the blocks, and only minor relief.  I am now on MS contin for pain.  In the Toronto area, there is a pain clinic at  The Toronto Western Hospital.  I've just been accepted to the pain clinic and will be tested in  depth in June.    Good Luck
