I reckon achilles injuries are one of the worst as they are so difficult to get rid of. I did mine about 15 months ago and after treament I was just about getting back to some degree of fitness when I went over on the ankle of the same leg spraining it very badly. It has taken 11 months and it is still not one hundred per cent. People have said to me in the past that a sprained ankle can be worse than a break. I used to scoff but am beginning to think they may have a point.
