Shoulder and neck pain

Your neck and shoulders contain muscles, bones, nerves, arteries, and veins, as well as many ligaments and other supporting structures.Many conditions can cause pain in the neck and shoulder area. Some are life-threatening (such as heart attack and major trauma), and others are not so dangerous (such as simple strains or contusions).

What Causes Neck Pain?

Causes of neck pain include:

  • Abnormalities in the bone or joints
  • Trauma
  • Poor posture
  • Degenerative diseases
  • Tumors
  • Muscle strain

What Causes Shoulder Pain?

The shoulder is a ball and socket joint with a large range of movement. Such a mobile joint tends to be more susceptible to injury. Shoulder pain can stem from one or more of the following causes:

  • Strains from overexertion
  • Tendonitis from overuse
  • Shoulder joint instability
  • Dislocation
  • Collar or upper arm bone fractures
  • Frozen shoulder
  • Pinched nerves (also called radiculopathy)

The most common cause of shoulder pain and neck pain is injury to the soft tissues, including the muscles, tendons, and ligaments within these structures. This can occur from whiplash or other injury to these areas. Degenerative arthritis of the spine in the neck (cervical spine) can pinch nerves that can cause both neck pain and shoulder pain. Degenerative disc disease in the neck (cervical spondylosis) can cause local neck pain or radiating pain from disc herniation, causing pinching of nerves (cervical radiculopathy). Abnormal conditions involving the spinal cord, heart, lungs, and some abdominal organs also can cause neck and shoulder pain. Here are some examples:

  • Broken collarbone: Falling on your outstretched arm can cause your collarbone to break. This is particularly common when cyclers fall off of their bicycles.
  • Bursitis: A bursa is a sac over the joints to provide a cushion to the joints and muscles. These bursae can become swollen, stiff, and painful after injuries.
  • Heart attacks: Although the problem is the heart, heart attacks can cause shoulder or neck pain, known as “referred” pain.
  • Broken shoulder blade: An injury to the shoulder blade usually is associated with relatively forceful trauma.
  • Rotator cuff injuries: The rotator cuff is a group of tendons that support the shoulder. These tendons can be injured during lifting, when playing sports with a lot of throwing, or after repetitive use over a long time. This can lead to pain with motion of the shoulder due to shoulderimpingement syndrome and eventually to a chronic loss of range of motion of the shoulder (frozen shoulder).
  • Shoulder or A-C separation: The collarbone (clavicle) and shoulder blade (scapula) are connected by ligaments. With trauma to the shoulder, these ligaments can be stretched or torn.
  • Whiplash injury: Injury to the ligamentous and muscular structures of the neck and shoulder can be caused by sudden acceleration or deceleration, as in a car accident. This can also cause muscle spasmsin the neck and shoulder areas.
  • Tendonitis: The tendons connect the muscles to the bones. With strain, the tendons can become swollen and cause pain. This is also referred to as tendinitis.
  • Gallbladder disease: This can cause a pain referred to the right shoulder.
  • Any cause of inflammation under the diaphragm can also cause referred pain in the shoulder.
