One of the most common forms of pain I see in my practice is neck and shoulder pain. Many people have jobs that require the muscles of the neck and upper back to work overtime to keep proper neck posture. Sitting in front of a computer all day or being stuck in a car or truck for example will eventually cause these muscles to become strained and develop trigger points. These trigger points will then cause pain, referred pain, stiffness and weakness. Neck and upper back trigger points will refer pain into the neck and head.
