btw, i mean that the helpline will tell you whether to see a GP, rest it or watever, not whether you broke ur wrist.
When I was practising jumping backwards over a wall (stupid I know) I fell over onto my wrist and injured it. I think I helped healing it by doing Push Up on my fists. At first it hurts (and sometimes burns away the skin) your hands but once your knuckles get strong enough it becomes easier (and a more efficient way to do Push Ups) and hopefully, like mine, your wrist will get stronger.
This could be wrong and it may injure your wrists more so don't do it unless you think it will work.
