ta jegsy, the woman i got via NHS sorted out an achilles thing a couple of years back and it was a very easy fix.
I'm hoping this will turn out to be too...i had a tiny little 100m jog in work shoes and with no warming up yesterday and it just felt a bit tight, so maybe it's just really tight and needs loosenign by the stretching and running!
time will tell and next appointment 2 fridays time!
