My left calf when i run HURTS ! why?
When i run my left calf becomes unbelievably sore, to the point where i have to stop running, it feels as if near the middle of my calf is going to explode out of my leg if i had to describe it. Why does this happen is it a pulled muscle or something and how can i fix it ? (It usually starts to hurt about 7 or 8 minutes into the run i guess and i just keep going until it hurts too much and i have to stop)
