I have/am still suffering, it's been 9 months now and I'm running about 15 miles a week Recently. When I first did it, it hurt a lot at first and then got worse, after 4 days I couldn't walk, and had to check myself into the local minor injury walk in centre. Left on a set of crutches with my chances of doing the Edinburgh marathon in tatters, I gave it three months doing nothing.. And I mean nothing, and then I started with 2 mins walk, 2 mins run with some complete beginners at my local club. Since then I've built up but it's still there, I've kind of accepted that its something that I will have to manage and live with, as I can't imagine it not being there now. I found compression calf socks helped, and loads of post run stretches and ice etc keep it from flaring up. It's bad news though and really hits your confidence as you worry it'll go again whenever you step up a level or run in unfavourable conditions.
