Burning, Stabbing sensation in left calf

Whenever i do calf raises i get this burning sensation in my left calf muscle when I fully raise up it feels like a knife stabbing me in my calf. It happens on workouts of 10 reps and up. I used to be able to do reps of 30 to 50 but the pain is too much the only thing i can do to workout my calves is go heavy and keep the reps low. The pain isn't as bad when i go lower since i don't have to tolerate it as long.

I took two months off from working calves stretching in the meantime but when I started working out again it was still there. Any other activity i do is pain free (i.e) walking, running, cycling but the minute i do calf raises especially high reps i get that burning sensation. Has anybody else had this problem and what did you do to fix it?
