All I can do is walk or stand, due to my sciatic nerve pain, so I got permission to walk back and forth in the back of the church yesterday during the service. I probably walked a mile while it all went on. I felt good. I can lay down too, it is just sitting that hurts so! I am in physical therapy for this too, so I have exercises I do for that twice a day. I only did them once yesterday, that was all I could muster up the courage to do, because some of them hurt to do. I know: "No pain, no gain." as they say. I am trying to bear with all this, but it is really tough!
