We all know what twitches feel like, had them for a long time. But this is kinda different, its like if you hold your muscle a certain way the muscle trembles....sometimes it will stutter to get into the right position.
I notice if i tense/hold my hand a certain way, the pad under the thumb will go off. Or, after i use my hand and then put it on a surface, it looks like the skin between index and thimb trembles for 2 seconds and then puts itself in its proper place.
Or if you pull your foot or hand back, once u release it it trembles. Its weird. Not sure if its normal thing? Do u know what these are that im talking about?
