Lower calf muscle - always pulling

Hi I am hoping for some advice, I have a cycle of lower calf muscle tightening, been to physio and it was worked out, but months later after running it gets tighter and tighter to such an extent I go for a run, do a 100 m and it pulls, i need help with good stretches, physio believed last time it was tight hamstrings where they join the gluts but struggle with knowing what stretches are for these specifically.

are you warming up before you run - or just blasting straight out of the blocks?  Compression Socks / Calf Guards might help... something like this

....if you can't control the amount of rolling in your leg/foot does then you'll continually overload the calf. Have a good long hard squizz at your shoes, foot type and lower limb control.

Great thnaks, bought some compression skins for my legs, also had a debate with some other runnrs and they also think it may actually be my achilles and suggested achilles stretches as well. Thanks again will give it a whirl and let you know.

I've got same problem.

Has anything worked?
