In the end I bought a decent ankle strap, kept sticking my foot into a basin of iced water, and kept it elevated. Much improved. Did my first run today (back to the start of C25K, and will stick to it this time).
Cheers Andy - i'll give it a try. It's such a frustration. I have never run 6k before and it felt so good. I obviously need to take it slower. I think it's more muscular than joint. The left hand side of my left foot. I'm going to keep going with the ice regularly - hopefully it won't be too long!
I'm not running now - using ibuprofen until it get's better. Ordered an ankle strap as well - probably can't do any harm. I'm wondering if it's more muscular - possibly along side of foot rather than ankle. I'll keep icing a nd hopefully it will recover quickly.
Cheers both - I never thought of the training schedule as preventing injury - just as increasing fitness. I am now taking regular ibuprofen - didn't know about not using heat - have been alternating heat and ice - will cut the heat out - why is that by the way?
There is a bit of pain at the back, but more to the side, I'll check out the website Debra - thanks for the advice.
