Muscle Twitches

Over the last week, I have been experiencing what seems like muscle twitches on the back side of my left hand that makes my index finger move towards my thumb.  They come and go throughout the day, but I have noticed that they subside with any sort of activity with my hand and fingers.  I notice them the most when my hand is at rest.  My hand, fingers, and forearm muscles look the same bilaterally and I don't have any noticeable weakness.  What could I be experiencing?

You are experiencing muscle twitches. (fasciculations)

If they only occur when your muscles are at rest then it is a fairly safe bet they are benign, if however you have weakness as well then it is time to worry a little more.

They are annoying and distressing none the less.

google BFS then you might not be so anxious about it.

How much weakness is considered a problem?

An inability to grip things, dropping things, finding it difficult to lift a heavy cup, that would be worrying, but muscle twitches that are not present when the muscles are active sound benign to me.

so, if fasciculations occur only at rest, then they are less likely to be ALS.  I'm asking because I developed calf fasciculations about a month ago.  About the same symptoms as above but just in my right calf.
