Good morning to one and all. I would like to introduce myself to all you good people. I live in London and have been off work the last six months with severe back pain, caused by lumbar spinal stenosis and three bad discs, lower back. I plodded on working the last three years with severe pain, having to sit at bus stops, steps, on the way home from work. Six months ago the pain was so bad in my leg and lower back I just wanted to lie flat on the ground.
