Plantaris muscle : The plantaris muscle starts just above the back of your knee and goes down to your Achilles tendon at the heel. It is right in the middle of your calf. It doesn't stretch well. If overstretched It could give symptoms similar to what you described. Stretching the calf muscles by letting heels drop with balls of feet on a step usually helps.
