I fell over on my slippery wooden decking, down from one level to the next ( about 1m) and put out my arm as you do instructively. So my wrist hurts and edge of my knee, but I can move my wrist it and all my fingers. It hurts to push or lift and I've taken painkillers but it's a mild hurt at rest, increased pain if I do anything. Chances it's just bruised ?
