Bursitis

by Cynthia M. Johnson, MA

Definition

Shoulder
Elbow
Knee
Hip

Bursitis in the Shoulder

Causes

Bursitis may be caused by:

Injury to an area that contains a bursa
Repetitive stress on the bursa
Infection in a bursa
Long periods of pressure on a joint, such as leaning on elbows, sitting, or kneeling on hard surfaces
Health problems that cause inflammation in joints, such as rheumatoid arthritis and gout

Risk Factors

Things that may raise the risk of this problem are:

Repetitive motions, such as swimming, running, or tennis
A job that requires:
- Repetitive motions, such as hammering or painting
- Long hours in one position, such as a kneeling to put down carpeting
Contact sports
Sporting gear that is too tight
A puncture or deep cut that involves the bursa

Symptoms

Bursitis can cause:

Pain
Swelling
Reddened skin
Warmth around the area of the bursa
Decreased motion of the nearby joint
Decreased movement or strength of the nearby limb

Diagnosis

The doctor will ask about your symptoms and past health. A physical exam will be done. This is often enough to make the diagnosis.

Treatment

The goal of treatment is to ease pain and promote healing. Choices are:

Supportive care, such as resting the area and applying cold compresses
Medicines to ease pain and swelling, such as:
- Over the counter pain medicine
- Steroids
Physical therapy to promote strength, flexibility, and range of motion

People who are not helped by these methods may need surgery.

Prevention

To lower the risk of this problem:

Exercise regularly to keep muscles strong
Slowly increase the intensity and duration of activities
Use the right safety gear and techniques when playing sports
Use proper safety equipment at work
Take breaks from repetitive tasks
