Hi I started my running career with couch2 5K about this time last year and got right into it up until the turn of the year when I seemed to be dogged with minor health problems. Then I did my back in, not quite sure how but it started about ten weeks ago after a fit of coughing. Anyhow it turns out that I have two issues with my back the more serious being the disc prolapse pressing on my spinal cord, which is causing weakness in both legs along with numbness and tingling. Walking is very difficult and I lose my balance a lot. I am due to go for an urgent operation to resolve the issue and was wondering how long I can expect to be out of action for?
