The more you walk the better you feel! I am 17 days post surgery and I feel great! I know exactly what you are talking about with the pain in your left shoulder, I thought I was dying! It will go away soon, but walk, walk, walk!! Also, butternut squash soup is yummy, there are a few brands that are low enough in sugar and fat for you to eat! Much better than the broth. You are only days behind me, so you should start feeling better very soon!! Make sure you drink lots of water!! Be happy! You have taken a huge step to make your life better!!
