Vampire, how old are you? This can affect recovery time.
I stuffed my ankle up last year....the end process of years of more minor injuries. The thing took 6 months before I could run normally again but the real issue is 'going for it' on rough descents.
I looked at Andy Murray...he plays top level tennis with ankle braces. So I took a leaf out of his book and got an aircast ankle brace. Not cheap at £50 but it makes ALL the difference. I now race and train in it. It lasts about a year before it wears out. But I can honestly say you don't notice it when running and it gives you the confidence to go hard.
Try one...here it is. http://www.physioroom.com/product/Ai...LHcaAtBD8P8HAQ
