Mine started in my right great toe after falling down a flight of stairs. I initially was diagnosed with turf toe and bone spurs. My RSD started after I opted to have the bone spurs removed. It as since spread to my left foot and other areas of the body. There are days when my husband can't touch the entire right side of my body from toe to shoulder. I am now disabled due to the amount of pain I am constantly in. Sorry no lefty mine started on the right.
