Pain in my arm

A
Has anyone had any weird sharp pain in their finger, hand, or arm? Woke up this morning and I kept getting the sharp pains from my shoulder to the tip of my fingers. It kind of feels like that moment when your foot has been asleep for a while and you try moving it and it kind of feels like little shocks. (Idk how to explain it lol). But it hurts and the majority of the pain is in my middle finger and hand. If I rub my hand against anything, it sends even more sharp pain throughout. The skin on my left hand is so sensitive. No where but the ER is open on weekends, so I am stuck waiting for Monday to make an appointment.
