Hes's physio sounds like he knows his runners to me! My ankle injuries are an annual delight now, except this year i've had to write off the whole spring/summer instead of trying to wing it. I've never had any luck with trying to run through ankle injuries, my latest is a pretty nasty Anterior Talofibular Ligament strain, and all the strength has left my ankle completely. My only saving grace is that the Strid Wood trail has around 1000' of climbing in it.
