Angie - I have spinal stenosis, narrowing from L-4 to S-1 and knee issues and orthopedic surgeon will not replace knees because if I were to fall, major issues. Over the years, sports and jogging has taken its toll. Getting jell shots in knees and cortisone shots helps somewhat. Yet, I push myself to walk. In dead winter, I walk inside house and my office. Mall is terrific idea. I live in small beach community, no malls within 30 miles. Before walking I use topical cream with Lidocaine. We all have to figure out what works best and keep moving. Ed
