I don't know exactly what's wrong but something is wrong with my ankle. On Friday I decided to cut my speedwork session as in the warm up I had pain in my ankle that caused me to limp a little. Anyway, I rested on Saturday and it felt fine but 20 mins into my long run today, Sunday, I got the pain back again and cancelled this run too.
The pain is a throbbing aching pain that feels like it's coming from deep inside and envelopes the whole area around the ankle. Yet when I stop running or only walk the pain goes away, although I still have a strange sensation there.
I will rest up today and tomorrow and try again on Tuesday.
