Are there any implications of sharp neck pains (left side)that come and go intermittently? almost like a stab,not tender or stiff.

Neck pains: Shooting,sharp neck pains are usually related to pinching of nerves by spurs or disc disorders in the neck vertebrae. Another cause is excessive tension in the muscles of the neck although you don't have chronic neck tightness or limitation of motion. If symptoms worsen a neurologist is best to evaluate and advise you about imaging tests and physical therapy and/or soft neck braces.
