Torn calf muscle, when should i seek medical advice?

Immediately: If you have truly torn the muscle in your calf, you should see your doctor right away. The longer you wait, the more difficult repairing the torn muscle will be.

Now: You are at greater risk for venous thrombosis. You should seek medical assistance immediately and possibly have testing and an ultrasound done. It may be a more dangerous condition than a "torn calf muscle".
