Arthritis and Bursitis
What Is Bursitis? Bursitis is the inflammation or irritation of the bursa. The bursa is a sac filled with lubricating fluid, located between tissues such as bone, muscle, tendons, and skin, that decreases rubbing, friction, and irritation.
What Causes Bursitis? Bursitis is most often caused by repetitive, minor impact on the area, or from a sudden, more serious injury. Age also plays a role. As tendons age they are able to tolerate stress less, are less elastic, and are easier to tear.
Overuse or injury to the joint at work or play can also increase a person's risk of bursitis. Examples of high-risk activities include gardening, raking, carpentry, shoveling, painting, scrubbing, tennis, golf, skiing, throwing, and pitching. Incorrect posture at work or home and poor stretching or conditioning before exercise can also lead to bursitis.

Stress or inflammation from other conditions, such as rheumatoid arthritis (http://www.webmd.com/content/article/78/95599.htm), gout (http://www.webmd.com/content/article/78/95591.htm), psoriatic arthritis (http://www.webmd.com/content/article/78/95622.htm), thyroid disorders, or unusual medication reactions may also increase a person's risk. In addition, an infection can occasionally lead to inflammation of a bursa.
Who Usually Gets Bursitis? Bursitis is more common in adults, especially in those over 40 years of age.

What Are the Symptoms of Bursitis? The most common symptom of bursitis is pain. The pain may build up gradually or be sudden and severe, especially if calcium deposits are present. Loss of motion in the shoulder -- called "adhesive capsulitis" or frozen shoulder -- can also be a sign of bursitis.
How Can I Prevent Bursitis? Bursitis can be prevented with a gradual buildup in activities, with limited force and limited repetitions. Stop what you are doing if unusual pain occurs. Try again later and if pain recurs, do not continue the activity that day.
How Is Bursitis Treated? Bursitis can be treated in a number of ways, including:


Avoiding activities that aggravate the problem.
Resting the injured area.
Icing the area the day of the injury.
Taking over-the-counter anti-inflammatory medicines (http://www.webmd.com/content/article/78/95603.htm).

If the condition does not improve in a week, see your doctor.
Your doctor can also prescribe drugs to reduce the inflammation. Corticosteroids, also known simply as "steroids," are often used because they work quickly to decrease the inflammation and pain. Steroids are also one of the safest treatment methods and can be injected directly at the site of injury. Unfortunately, 30% of people may not get complete relief from one injection. Another disadvantage is that for recurrent cases, it is not safe to administer steroids frequently (more than every four months).
Physical therapy (http://www.webmd.com/content/article/78/95615.htm) is another treatment option that is often used, especially for a frozen shoulder. This includes range-of-motion exercises and splinting (thumb, forearm, or bands).
Surgery, although rarely needed, may be an option when bursitis does not respond to the other treatment options.
Warning Consult your doctor immediately if you have:


Fever (over 100 Fahrenheit)
Swelling, redness, and warmth
General illness or multiple sites of pain
Inability to move the affected area

These could be signs of another problem that needs more immediate attention.
