Yesterday I cleverly (or not!) managed to trip over my 7 year old son while coming downstairs resulting in a verypainful knock/twist to the right side of my right ankle (lateral malleus or something like that). Today, GP said possible fracture

, but X-ray revealed nothing

.
Question: How long should i stay off diving after I can walk without limping? [Ankle currently supported by tubigrip bandage (3 layers).]
