DS broke his leg last Sunday and had surgery yesterday. As he has to keep his leg elevated for another 1-2 weeks I am wondering how to help him with the pain he is having at the base of his spine (his tailbone) - caused obviously by having to lie down/sit up with his leg up and extended 24/7. He is having regular pain relief anyway but it doesn't seem to be helping with this particular aggravation. Any advice please?
