I Have Been Running And Doing Tumbling For A While

I have been running and doing tumbling for a while and 2 weeks ago my calf muscle hurt but I didn't tell anyone and now it hurts extremely bad. When I flex/turn my foot to the left and when I jump or run. It is my left leg and the right dosent hurt at all I kinda thought it was possibly a torn or pulled muscle but I just wanted to make sure.
