I know you are concerned for your sister. She is just a few days out of the surgery. I was in bed for the most part for two weeks. Got up to get moving a bit, walked in the garden a bit, but really did lay low for that two week period of time. The pain was severe for me. I also had arm pain, weakness, and eventually it did go away. I am fused C3-7. Have faith that in time she will recover fully. Depression can also happen cause you hurt and are stuck in bed. If she can read, or watch TV, any kind of distraction helps while you are healing. I will be here to listen. Ginnie
