Hi, I am a 53 year old male, and I have always been involved with sports, especially rugby which I played for 12 years. After I stopped playing I continued exercising and lifting weights, quite heavy and never had a problem. Lately I noticed that I could not get a push off from my left calf, which has affected my walking and definitely running. I was diagnosed with stenosis. I have no pain at all, just the issue with my calf. Is surgery, even minimal, my only choice? I have seen that there are no really good alternatives as far as medication or therapy. How could the abnormal growth in the vertebrae be reduced?Thank you
