It's annoying, but not painful, and comes and goes. You can actually see the muscle twitch when it happens.

It's also possible to have what neurologists call benign fasiculations--occasional muscle twitches with no real observable cause beyond a slightly stronger than normal nerve signal going down the motor nerve from time to time. Still, given your history, it might be worth an exam and some localized neuromuscular testing.
