Frank I don't have an answer except at one time I couldn't even do my shoe laces up, so I had all the usable pain killers xrays etc telling me there was nothing wrong I bought and inversion table use it 5 minutes a day for a month and all my pain disappeared it separates the vertebrae which gave the pain and if you build up the muscles in the back then you won't need to use it again. I'm not saying this will work for you but there's a chance. I love the PC fan idea by the way. Roly
