Maybe: If I were you I would want to know why this was occurring.It could be a variety of causes,one being something called Raynaud's phenomenon.There could also be a nerve impingement farther up in your arm(s) that would be concerning if it were occurring out of the blue.It may be something benign,but I would advise to see your doc and investigate it further to make sure nothing more serious is going on
