I get this all the time, and my running friends get it too. I think the correct description is a
muscle "fasciculation" (probably spelled wrong). Its probably a fairly normal response to exercise.
When you're running, your muscles are contracting repeatedly for an extended period. The metabolism
of the muscle cells has to increase to keep up with the demand. When you stop excercising, the
muscle cells are still in a high metabolic state, but are no longer being used. The increased
metabolism make the muscles hyperexcitable, as they wait for the next nerve impulse to contract.
When the impulse doesn't arrive, the hyperexcited muscle cell eventually just contracts on its own.
The "bubbling" you see is just individual muscle bundles contracting own there own. It's probably
harmless. I usually don't even notice it unless I happen to look down at my calves after a run.
If it bothers you, you might try a longer cool down period after your runs. Try a slow jog, or walk
for 15 minutes after your workout.
