 Pain and other symptoms in the arm and shoulder may be due to
injury of the neck or cervical spine. The seven cervical vertebrae (spinal bones) in the neck have highly mobile joints so that you can
bend and tilt your neck. Since the neck is exceptionally flexible, it is susceptible to injury and pain which can be referred to the shoulder
and the arm. (It should be noted, however, that pain in the arm and shoulder may be due to other conditions not related to the cervical spine such as frozen shoulder, strain/sprain syndromes, osteomas,
etc.)
The vertebrae are separated by discs, which are stiff jelly like pads that act as elastic cushions between the spinal bones. Neck,
shoulder and arm pain may be caused by an abnormal bulging or protrusion of a disc in the cervical spine, The disc may impinge on the spinal nerve roots or irritate the spinal cord itself. This is also
known as a herniated or slipped disc.
Cervical disc lesions that can cause arm and shoulder pain can be acute or chronic. For example, sudden and severe pain (acute
torticollis) can result from lying too still for too long, on a pillow too thick or too thin, or in a position that keeps the neck in a sideways position for a long period.
Another way of developing acute torticollis is a whiplash injury or by simply stretching. Severe neck
stiffness can result, sometimes with discomfort in both arms, and pins and needles in the fingers.
 Pain in the shoulder blade (the scapula) may also be due to cervical
disc trouble. It is also a common site for referred pain secondary to gall stones or a transverse humeral ligament tear or rupture. This scapular
pain may radiate from the shoulder blade up to the base of the skull. Pressure on the nerve that innervates the arm area (the brachial nerve) from cervical disc injury can also cause pain in the shoulder, arm and
chest.
Still other causes of shoulder and arm pain may include referred pain, such as from a heart attack, as well
as regional disorders of the shoulder, elbow, wrist and hand. These conditions may include osteoporosis, tumors or cancerous growths, bursitis, neuritis and damage to the nerves and spinal cord.
