question: I have two spinal can stenosis at the L4 L5 , severe facet arthritis and one disc is now sitting on a nerve. I am allergic to aspirin and NSAIDs and use Tynalol extra strength. I am 63, swim 2 km a day, participate in Tai Chi and am considering Nordic Pole walking. I was a teacher and now am on LTD. I am just wondering about this in the long term.
