My injury I had last December also gave me carpal tunnel issues in my left forearm. They did it back in August and it hurt for awhile. The biggest thing to watch for is stiffness in the wrist but I can't say how well it worked because the RSD that has been screwing up my hand hurts so bad that I can't say what it would have felt like if it did work. The surgery though was quick with a row of stitches in the palm.
