Your neck supports the weight and movement of your head which, considering an adult’s head can weight between ten and fourteen pounds, is a very demanding job. Neck pain may often be caused by the long-term effect of bad posture aggravated by the amount of driving, computer work and TV watching that most of us do. It is not suprising that neck pain is one of the most common complaints chiropractors see.
Injuries or stresses to the neck can cause loss of proper joint movement which may in turn cause irritation of the nerves that come out of your spine. The nerves of the upper neck supply your scalp and the nerves of the lower neck supply the arms. Therefore a pain in the arm or head can actually be a pain in the neck.
