well a positive update: as some of you know I have been on light doody since February due to a knee injury. Went to knee specialist A few weeks ago and he said that knee replacement was not an option for me due to the nature of my work. He recommended a cortisone shot and prescription an anti-inflammatory. He also said I'm already doing the best thing by losing weight, (80lbs since Feb 18th). So now 3 weeks later and I am back to full doody and pain free so far!
