I doubt you will see nerves "moving".... You may see an arterial pulse which will match your pulse if you take it in your wrist at the same time.

You are probably seeing tendons twitching, or muscles rippling.

I'd do the magnesium lotion on the tops of your feet each night.
Use a quarter's diameter divided in half for each foot, rub it in up to your ankles (including them if it goes that far). This will open up your circulation and help with the muscle twitching.
