Left total knee replacement 3 years ago. Recently diagnosed with stenosis T10-11, after experiencing numbness in bilateral feet, worse on left side- numbness went to knee area. Previously active but went from walking with cane then to walker. Surgery 4/28/15 spinal fusion T10-T12. Recovering well from surgery, still have numbness in feet but improved., walking with cane. I was experiencing some Lt. Knee pain prior to surgery but now am in significant pain. Extreme tight feeling in knee, most on top and high front of knee. Have tried cold packs and heat- heat seems to help a little more. Taking Aleve. I am also taking oxycodone prescribed following back surgery for back pain and it is not helping knee. Thank you for your help
