I have just joined this forum from Brisbane Aust. In 2006 my trouble started with a severe burning sensation in my right leg. Discovered the problem was Spinal Stenosis and was referred to the Neurosurgery area at Brisbane Hospital. The registrar gave me some very comforting news when he said" Back operations for leg pain are 95% successful while operations for back pain are a different story". I had the surgery in March 2007 and it was successful. The leg cramping I had before the op. was gone. Was left with Peripheral Neuropathy which will be with me forever. As long as I wear the right shoes I can walk for 2/3 hours. Driving is now limited to about 20 miles before the feet cramp up like blocks of wood. Hope this helps others with this problem.
