I have some advice for anyone who ever sprains their ankle, rest it rest it rest it rest it REST IT!
Because I didn't, I really regret not giving my tendons time to repair themselves and now both of my ankles are very weak, if I sprain either of my ankles again I might not be able to use them properly for 6 months! (that means no running!)
I thought that because I'm only 20 that my body would recover quickly, but ankles don't work that way, I was ignorant and arrogant to think I could fool them!
Ankles are your friends! Treat them well and rest them when you hurt them!
Andy Murray also suffers from weak ankles! (check out those ankle supports!)
