I had an MRI showing severe Stenosis and other problems. I am 75 years old and play tennis 4 times a week. I been dealing with numbness for 4 years. Try meds and PT and no improvement. Went to Neurosurgeon in Athens. Ga. Doctor Shashikant Patil who reviewed the MRI which showed almost a complete closure of spinal canal in Lumbar area. PS... he sent me for a nerve conduction test before he would see me. Hope that helps with your questions. The Doctor is monitoring my situation. Just wanted to see if anyone could share if they had similar experience.
