Well, here's the latest news ...
Went for another run/walk on Saturday afternoon. And on Sunday too and the right ankle was painful both times. On a scale of 1 to 10 where 1 is almost no pain and 10 is unbearable - walking is almost zero and running was about 7 or 8. The difference was incredible.
The injury obviously hasn't healed so I'm going to see a couple of specialists at Leeds General Infirmary tomorrow (including a musculo-skeletal guy who happens to a be a runner). We will get to the bottom of this.
So ... lots of tests tomorrow. CT scan, blood, balance, X ray, etc
I'm still doing lots of strength work, cycling and stretching for the moment. I'm not sure if that's helping or hindering but I feel better for doing it. Again I'll know more in a few days time.
