Yes, I Have Problems With Spinal Sconosis ? And Experiencing

Yes, I have problems with spinal sconosis ? and experiencing pain when walking and leg cramps that are sometimes severe. I have always been fairly active and an avid hiking and this is really depressing . I alsi have the sleep apena ? and wondering if that's causing the cramps maybe more so then the arthritis in spine? I also need a good anti-inflammatory as the current one doesn't seem to do much. I once took one prescribed by a dentist, and it worked super well for my arthritis until it started eating my stomach up. It was an oblong bluish or purple color around ten years. Weird name, kind of like "difumsical" Any ideas? Thanks
