Severe arm and hand tingling like electric shock when i tilt my head back also neck pain arm numbness?

Radiculopathy: It sounds like a disc has herniated in your neck or some other issues closing off the opening your nerve roots run through to exit the cervical spine. These are classic symptoms and I recommend seeing a physician sooner than later to identify if there is anything emergent or surgical necessity to avoid arm paralysis. You may not need anything but a Medrol (methylprednisolone) dose pack, but get checked to be sure.
