Oh poor you squaredog. I broke my left wrist three years ago after falling on the ice by my garden gate. I wasn't allowed to go to work (nursing) for seven weeks. I just about went crazy. I read loads and did puzzles. The best exercise for it when the plaster came off was to do press ups against a wall . Put your hands, with arms outstretched, against a wall. Then push in and out. The physio said I'd probably regain 80% use of it, but I actually now have full use of my arm. I now dislike ice intensely, except in a drink.
Parents-in-Law. What do/did you call them?
