My fingers on my left hand keeps getting stuck in the bend position when I try to lift them.....its like trying to lift your fingers and someone is pulling them back down..... Like my muscles get stuck but with a pulling sensation it last for about 1-3 seconds which might not seem that long but it is when something scary like thus happens..... It feels like I've gripped something tight and now my fingers are use to that position..... Sorry if this seems to be all over the place its just kind of hard to explain.....I kinda remembering this happening before but it was a while ago! Have anyone had this happen or know what it is?
