My fingers (thumbs in particular) have been twitching for the past two days or so, I really noticed it two days ago after I lifted but I still didn't really know the source.
So just now I did a few deadlifts and now my thumbs and wrist/hand in general have been heavily twitching. Is this a normal thing or should I be worried?
For what it's worth I have two great grandparents (one maternal and one paternal) who had Parkinson's, but the twitching only seems to affect my fingers and any other muscles while they are extended or in light use, not while at rest or in fast motions.
