Can you tell me how to cure neck pain for good?

Neck pain. Please specify in details of your neck pain symptoms. Severe? Sharp or dull? Constant or intermittent? Any pain radiation down to shoulders or arms? Any numbness or tingling in hands or fingers? Any motor weakness in upper extremities? And finally, what caused your neck pain?
Cure unlikely. You may be able to manage your neck pain via exercise, diet, and medications/treatments, however cure is typically rare. Please consider seeing a spine specialist to see what your options for pain control are.
