On both occasions when the calf’s tightened up, it’s been inside 10 minutes of finishing my workout. It hasn’t stopped me from running or given me pain during the workout.

If the injury were a serious tear, it would’ve come on during the workout, as if something had torn and I’d be unable to run, right? I was sprinting 100m reps as fast as ever minutes before it came on the first time, but the stiffness was within minutes and very severe, to the point of affecting my walk.

On the other hand, it’s 25 days since the injury first came on and progress is very slow… I can walk perfectly, but get discomfort in the Gastrocnemius when going up and particularly down stairs…

Using a foam roller seems to have a positive effect, albeit very slight. Should I restrain from stretching until all discomfort is gone? There is what I’d call a ‘discomfort’ rather than pain at this point – but it almost feels more like a nerve-type pain, as opposed to a muscle tear… The strength of the calf seems ok – it’s impact when landing that causes discomfort.
