In reply to Bob Kemp:
At the physio we probably did an hour measuring range of movement and strength, usually low on the injured side, plus a lot prodding! You'll have to rest, but keep it mobilise at first, then I did a mixture of calf raises, double and single legged, massage, stretching, rubber band exercises, balance work ... there's a lot going on in the region, so there isn't really a simple or quick solution.
Even if you don't run consider a trip to a running shop with sensor pads, so you can see how your feet land and roll etc... special inner soles aren't cheap but if they help then I'd consider them worth the cost.
