Re: Involuntary movement in right thumb and right foot.
a few years back, my right thumb got a weird spasm, it sorta cramp up and turned inwards, have the biggest panic attack about it.
I often got a tapping sensation in my baby toe, then one day I realized it was twitching.
I think it can happen when the muscles get tired.
I swear I had written out the above reply before I read the part about your toe!
In people that play video games too much , it's rather common for them to get twitchy fingers, so it could be over use.
Because it's only one finger, one toe twitching at a time, that's a good sign! (I googled so you don't have to )
low levels of magnesium can cause it, also read a study where magnesium can help animals with anxiety!
constant twitching can be cause by a compressed disk in your spine.
all in all it seems like it's pretty harmless : )
