SHOULDER PAIN
Overview
The shoulder has a wide and versatile
range of motion. When something goes wrong with your shoulder, it hampers your
ability to move freely and can cause a great deal of pain and discomfort.
The shoulder is a ball-and-socket joint that
has three main bones: the humerus (long arm bone), the clavicle (collarbone),
and the scapula (also known as the shoulder blade).
These bones are cushioned by a layer
of cartilage. There are two main joints. The acromioclavicular joint is between
the highest part of the scapula and the clavicle.
The glenohumeral joint is made up of
the top, ball-shaped part of the humerus bone and the outer edge of the
scapula. This joint is also known as the shoulder joint.
The shoulder joint is the most mobile
joint in the body. It moves the shoulder forward and backward. It also allows the
arm to move in a circular motion and to move up and away from the body.
Shoulders get their range of motion
from the rotator cuff.
The rotator cuff is made up of four
tendons. Tendons are the tissues that connect muscles to bone. It may be
painful or difficult to lift your arm over your head if the tendons or bones
around the rotator cuff are damaged or swollen.
You can injure your shoulder by
performing manual labor, playing sports, or even by repetitive movement.
Certain diseases can bring about pain that travels to the shoulder. These
include diseases of the cervical spine (neck), as well as liver, heart,
or gallbladder disease.
You’re more likely to have problems
with your shoulder as you grow older, especially after age 60. This is because
the soft tissues surrounding the shoulder tend to degenerate with age.
In many cases, you can treat shoulder
pain at home. However, physical therapy, medications, or surgery may also be
necessary.
Here’s what you need know about
shoulder pain, including causes, diagnosis, treatment, and prevention.
What causes
shoulder pain?
Several factors and conditions can
contribute to shoulder pain. The most prevalent cause is rotator cuff tendinitis.
This is a condition characterized by
swollen tendons. Another common cause of shoulder pain is impingement syndrome where the rotator
cuff gets caught between the acromium (part of the scapula that covers the
ball) and humeral head (the ball portion of the humerus).
Sometimes shoulder pain is the result
of injury to another location in your body, usually the neck or biceps. This is
known as referred pain. Referred pain generally doesn’t get worse when you move
your shoulder.
Other causes of shoulder pain
include:
- arthritis
- torn cartilage
- torn rotator cuff
- swollen bursa sacs or tendons
- bone spurs (bony projections
that develop along the edges of bones)
- pinched nerve in the neck or
shoulder
- broken shoulder or arm bone
- frozen shoulder
- dislocated shoulder
- injury due to overuse or
repetitive use
- spinal cord injury
- heart attack
How is the cause of shoulder pain diagnosed?
Your doctor will want to find out the
cause of your shoulder pain. They’ll request your medical history and do a
physical examination.
They’ll feel for tenderness and
swelling and will also assess your range of motion and joint stability. Imaging
tests, such as an X-ray or MRI, can produce detailed pictures of your
shoulder to help with the diagnosis.
Your doctor may also ask questions to
determine the cause. Questions may include:
- Is the pain in one shoulder
or both?
- Did this pain begin
suddenly? If so, what were you doing?
- Does the pain move to other
areas of your body?
- Can you pinpoint the area of
pain?
- Does it hurt when you’re not
moving?
- Does it hurt more when you
move in certain ways?
- Is it a sharp pain or a dull
ache?
- Has the area of pain been
red, hot, or swollen?
- Does the pain keep you awake
at night?
- What makes it worse and what
makes it better?
- Have you had to limit your
activities because of your shoulder pain?
When should I seek medical help?
You should contact your doctor if you
experience fever, inability to move your shoulder, lasting bruising, heat and
tenderness around the joint, or pain that persists beyond a few weeks of home
treatment.
If your shoulder pain is sudden and
not related to an injury, call 911 immediately. It may be a sign of a heart
attack. Other signs of a heart attack include:
- trouble breathing
- chest tightness
- dizziness
- excessive sweating
- pain in the neck or jaw
What are the treatment options for shoulder pain?
Treatment will depend on the cause
and severity of the shoulder pain. Some treatment options include physical or
occupational therapy, a sling or shoulder immobilizer,
or surgery.
Your doctor may also prescribe
medication such as nonsteroidal anti-inflammatory medications (NSAIDs) or corticosteroids. Corticosteroids are powerful
anti-inflammatory drugs that can be taken by mouth or your doctor can inject
into your shoulder.
If you’ve had shoulder surgery,
follow after-care instructions carefully.
Some minor shoulder pain can be
treated at home. Icing the shoulder for 15 to 20 minutes three or four times a
day for several days can help reduce pain. Use an ice bag or wrap ice in a
towel because putting ice directly on your skin can cause frostbite and
burn the skin.
Resting the shoulder for several days
before returning to normal activity and avoiding any movements that might cause
pain can be helpful. Limit overhead work or activities.
Other home treatments include
using over-the-counter nonsteroidal
anti-inflammatory medications to help reduce pain and
inflammation and compressing the area with an elastic bandage to
reduce swelling.
How can I prevent shoulder pain?
Simple shoulder exercises can help
stretch and strengthen muscles and rotator cuff tendons. A physical therapist or
occupational therapist can show you how to do them properly.
If you’ve had previous shoulder
issues, use ice for 15 minutes after exercising to prevent future injuries.
After having bursitis or tendinitis, performing simple range-of-motion exercises every
day can keep you from getting frozen shoulder.
