<s>[INST] 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 [/INST] Hi, you have been diagnosed as Lumbar Canal Stenosis, which is a common lumbar degenerative disorder. If you have developed weakness in your calf, it means it has progressed to severe degree. You will most likely benefit from surgical decompression. Halting progression of this needs' lifestyle modification like avoid lifting heavy weights, bending forward. Take advice from physiotherapist for correct posture and exercises. Thank you. </s>
