[|Human|] Would you please in layman s terms explain a condition called spinal stenosis. I have it in my neck and my lower lumbar. I also have arthritis in all affected vertabrea. lumbar. My Spinal Dr. is giving me 3 steroid injections over 3 weeks. The lumbar stenosis has been causing numbness and pain in my left leg and it has been too painful to walk my dog for 2 years.
[|AI|]  Thanks for posting your query in Chat Doctor, Spinal cord is the one which is present in the backbone of human body. It carriers nerves for sensation and for muscle action. The backbone is called vertebral column from which nerves emerge out and supply different organs in body. If the canal of vertebral column become narrowed they compress the nerves and cause numbness and pain. This narrowing is called spinal stenosis., and please click the link to see the image http://physioworks.com.au/images/Injuries-Conditions/spinal-stenosis.jpgthank you
