Ankle pain? Fell over awkward?

So I don't think I have done anything more than sprain it? Possibly bruise.. Anyway I saw running and somhow fell on it it really hurt but I was able to get up and walk on, about 10 mins after I collapsed on it and again I was fine with walking. So I get no pain when walking but when I put my foot in a point toe position it really hurts this also happens when it's moved left of right... Any idea on what may have happened? Or ways to make it less stiff when moving? Thanks xx
