I would see a chiropractor, you very well could have some pinched nerves in your back and neck, and if so, this will definitely cause the symptoms you mentioned.
Do you feel the need to shake them? Like shaking them calms the sensation? Or is it more like numbness? If it is numbness, it could be a back problem, If it is more the tingly, nervous, sensation, then not eating after 6 pm or avoiding foods high in sugar could actually help. Keep us posted!
that sounds like a nerve problem. which could be linked to something neurological or just a matter of a pinch somewhere. there's a wide array of things that could be causing your discomfort.
