I had the same thought as Judy...Does he say why he doesn't want to get up and move around. Pain would certainly be one reason he doesn't want to get up and move around. Once the pain is addressed, he'll probably start moving around more. Has he tried Beano or something similar for the gas? I had a friend tell me about it after she had surgery. She said it helped tremendously. Was Charlie's surgery done laparoscopically? If so, I have heard that that can cause terrible gas pains. His poor systems is still trying to heal and figure out what the heck just happened. Give it time. He'll come around once he is feeling better.

Hang in there! You are doing a great job of encouraging him and taking care of him. It takes a while to recuperate from such a major surgery.
