Still struggling on 9 months after what seemed like a relatively minor AT injury. Now on my second physio and hoping to start running again soon. Second physio recommends calf raises to strengthen calves and take the strain off the AT. Calf drops definitely work in the acute stage though. Slow controlled drops and use both legs to do the raise part.
In both cases, the injuries have occurred within 5minutes of commencing the run, so I suspect that hydration isn't the problem. Having had a quick look at the structure of the calf, I suspect it's damege to the gastrocmenius.
In both cases, it had happened whilst running downhill. Just wondering in my attempt at not heel striking, if I'm slamming my foot down too hard and shock loading the muscle.
