un explained muscle contractions

ever since i was little i would have muscle contractions that i couldn't stop but were not huge problems like slight ticks, an eye flicker my leg tensing up but for the most part i could just ignore it. It would mostly come on when i was extremely tiered so i put it down to that.

But now it happens more often and it is peculiar, on my right and on the lower edge (the pinky side) my palm will indent its self like some one is pressing an invisible cylinder like a pen against it.

has anyone else had this or something like it?
