Neck pain can be so mild that it is merely annoying and distracting.
Or it can be so severe that it is unbearable and incapacitating. Fortunately, most minor, posture-induced neck pain episodes clear up on their own after rest and efforts not to repeat the offending stresses on the neck. But neck pain that just won't go away after a day or so is a more serious matter. Neck pain that lasts for many days or keeps coming back is a signal that something isn't right. An expert must determine the underlying causes of such neck pain.
