A pinched nerve in the neck (cervical radiculopathy) is caused when the nerve that goes from the spinal cord to the neck or arm is irritated or has pressure on it. This may be caused by a bulging spinal disc. A spinal disc is the cushion between each spinal bone (vertebrae). Or it may be caused by bone spurs or a narrowing of the spinal joint because of osteoarthritis and wear and tear from repeated injuries.
A pinched nerve can cause numbness, tingling, deep aching, or electrical shooting pain from the side of the neck all the way down to the fingers on one side. It can also cause weakness of the muscles that the nerve controls.
A pinched nerve may start after a sudden turning or bending force (such as in a car accident) or after a simple awkward movement. In either case, muscle spasm is commonly present and adds to the pain.
