What is bursitis?
Bursitis is inflammation of a bursa. A bursa is a closed, fluid-filled sac that works
as a cushion and gliding surface to reduce friction between tissues of the body. The
major bursae (this is the plural of bursa) are located next to the tendons near the
large joints, such as in the shoulders, elbows, hips, and knees.
Bursitis is usually a temporary condition. It may limit motion, but generally does
not cause deformity.
Bursitis can happen in any bursa in the body, but there are some common types of bursitis.
Anterior Achilles tendon bursitis. This type of bursitis is also called Albert disease or retromalleolar bursitis. It’s
caused by things like injury, disease, or shoes with rigid back support. These put
extra strain on the lower part of the Achilles tendon. This attaches the calf muscle
to the back of the heel. This can lead to inflammation of the bursa located where
the tendon attaches to the heel.
Posterior Achilles tendon bursitis. This type of bursitis is in the bursa located between the skin of the heel and the
Achilles tendon. This attaches the calf muscles to the heel. It is aggravated by walking
that presses the soft heel tissue into the hard back support of a shoe. Walking in
shoes that repeatedly put pressure on the heel can cause the bone to enlarge at the
back of the heel. Examples of these shoes are high heels or pumps. This enlargement
is called Haglund deformity.
Hip bursitis. This is also called trochanteric bursitis. Hip bursitis is often caused by injury,
overuse, arthritis, or surgery. This type of bursitis is more common in women and
middle-aged and older adults.
Elbow bursitis. Elbow bursitis is caused by the inflammation of the bursa located between the skin
and bones of the elbow (olecranon bursa). Elbow bursitis can be caused by injury or
constant pressure on the elbow. For example, it can happen when leaning on a hard
Knee bursitis. Bursitis in the knee is also called goosefoot bursitis or Pes Anserine bursitis. The
Pes Anserine bursa is located between the shin bone and the three tendons of the hamstring
muscles, on the inside of the knee. This type of bursitis may be caused by not stretching
before exercise, tight hamstring muscles, being overweight, arthritis, or out-turning
of the knee or lower leg.
Kneecap bursitis. This is also called prepatellar bursitis. This type of bursitis is common in people
who are on their knees a lot, such as carpet layers and plumbers.
What causes bursitis?
The most common causes of bursitis are injury or overuse. Infection may also cause
Bursitis is also linked to other health problems. These include arthritis, gout, tendonitis,
diabetes, and thyroid disease.
What are the symptoms of bursitis?
The following are the most common symptoms of bursitis. But symptoms occur a bit differently
in each person. Symptoms can include:
Long-term (chronic) bursitis may involve repeated attacks of pain, swelling, and tenderness.
These may lead to the deterioration of muscles and a limited range of motion in the
The symptoms of bursitis may look like other health problems. Always see a healthcare
provider for a diagnosis.
How is bursitis diagnosed?
Your healthcare provider will ask about your health history and do a physical exam.
You may also need tests such as:
X-ray.This test uses energy beams to make pictures of internal tissues, bones, and organs
MRI. This test uses large magnets, radio waves, and a computer to make detailed pictures
of organs and structures within the body.
Ultrasound. This test that uses high-frequency sound waves to look at the internal organs and
Aspiration. For this test, the healthcare provider uses a thin needle to remove fluid from the
swollen bursa. The fluid is checked for infection or gout as causes of bursitis.
Blood tests. Lab tests may be done to confirm or rule out other conditions.
How is bursitis treated?
The treatment of any bursitis depends on whether it involves infection.
Aseptic bursitis. This inflammation results from soft-tissue trauma or strain injury. The bursa is not
infected. Treatment may include:
R.I.C.E. This stands for rest, ice, compression, and elevation.
Anti-inflammatory and pain medicines, such as ibuprofen or aspirin
Shot (injection) of a steroid into the affected area to help ease pain and swelling
Splints or braces to limit movement of the affected joint
Septic bursitis. The bursa becomes infected with bacteria. This causes pain and swelling. Treatment
What can I do to prevent bursitis?
Try the following measures to prevent bursitis:
Warm up before exercising or before sports or other repetitive movements.
Start new exercises or sports slowly. Gradually increase the demands you put on your
Take breaks often when doing repetitive tasks.
Cushion “at risk” joints by using elbow or knee pads.
Stop activities that cause pain.
Practice good posture. Position your body correctly when doing daily activities.
When should I call my healthcare provider?
Call your healthcare provider if you have any of the following:
Pain or trouble moving that affects your regular daily activities
Pain doesn’t get better or gets worse with treatment
A bulge or lump develops at the affected joint
Redness or swelling develops at the affected joint
You have fever, chills, or night sweats

Pain, swelling, and tenderness near a joint are the most common signs of bursitis.
Bursitis can be treated with rest and medicines to help with the inflammation. Antibiotics
are used if infection is found. If needed, surgery can be done to remove the bursa.
You can help prevent bursitis by doing things like warming up before exercise or sports,
increasing activity slowly, padding joints, taking rest breaks often, and stopping
activities that cause pain.
