my fingers from hands and legs mostly go rubbing against each other ,its more like i cannot control that, well if i put both my feet together touching each other some thing drives me to start rubbing my feet against each other. the same is with my fingers and when ever i get nervous or angry i gues i do this more , this is not a complete explanation of my problem but at a high level my fingers or my feet have the tendency to make movements uncontrollable by me its like something drives them even if i dont want to do that .
