Unexplained shoulder pain that does not change when you move your
neck, shoulder, or arm or that occurs with symptoms elsewhere in your body
(such as in your abdomen or chest) may be referred shoulder pain. Referred pain
means that a problem exists somewhere else in the body other than where you
feel the pain.
As recently as 20 years ago, people with chronic pain were too often dismissively
told that their problem was "in their heads" or that they were
hypochondriacs. But in the last decade, a handful of dedicated researchers
learned that chronic pain is not simply a symptom of something else -- such as
anxiety, depression, or a need for
attention -- but a disease in its own right, one that can alter a person's
emotional, professional, and family life in profound and debilitating ways.
A lung problem, such as
pneumonia, where pain may be felt throughout the
shoulder, shoulder blade area, upper chest, upper arm, neck, and armpit. Pain
is usually felt in the shoulder on the same side as the lung problem.
