Bursitis (bur-SY-tis) is a painful condition that affects the small, fluid-filled sacs — called bursae (bur-SEE) — that cushion the bones, tendons and muscles near your joints. Bursitis occurs when bursae become inflamed.
The most common locations for bursitis are in the shoulder, elbow and hip. But you can also have bursitis by your knee, heel and the base of your big toe. Bursitis often occurs near joints that perform frequent repetitive motion.
Treatment typically involves resting the affected joint and protecting it from further trauma. In most cases, bursitis pain goes away within a few weeks with proper treatment, but recurrent flare-ups of bursitis are common.
If you have bursitis, the affected joint may:
- Feel achy or stiff
- Hurt more when you move it or press on it
- Look swollen and red
When to see a doctor
Consult your doctor if you have:
- Disabling joint pain
- Pain for more than one to two weeks
- Excessive swelling, redness, bruising or a rash in the affected area
- Sharp or shooting pain, especially when you exercise or exert yourself
- A fever
The most common causes of bursitis are repetitive motions or positions that irritate the bursae around a joint. Examples include:
- Throwing a baseball or lifting something over your head repeatedly
- Leaning on your elbows for long periods
- Extensive kneeling for tasks such as laying carpet or scrubbing floors
- Prolonged sitting, particularly on hard surfaces
Other causes include injury or trauma to the affected area, inflammatory arthritis such as rheumatoid arthritis, gout, and infection.
Anyone can develop bursitis, but certain factors may increase your risk:
- Age. The occurrence of bursitis becomes more common with aging.
- Occupations or hobbies. If your work or hobby requires repetitive motion or pressure on particular bursae, your risk of developing bursitis increases. Examples include carpet laying, tile setting, gardening, painting and playing a musical instrument.
- Other medical conditions. Certain systemic diseases and conditions — such as rheumatoid arthritis, gout and diabetes — increase your risk of developing bursitis.
While you may initially bring your concerns to your family physician, he or she may refer you to a doctor who specializes in joint disorders (rheumatologist).
What you can do
You may want to write a list that includes:
- Detailed descriptions of your symptoms
- Information about medical problems you've had
- Information about the medical problems of your parents or siblings
- All medications and dietary supplements you take
- Questions you want to ask the doctor
For bursitis, some basic questions to ask your doctor include:
- What is the most likely cause of my symptoms?
- Are there any other possible causes?
- Will I need to have tests?
- What treatment approach do you recommend?
- I have other medical problems. How best can I manage them together?
- Will I need to limit my activities?
- Are there self-care measures I can try?
- Do you have brochures or other printed material I can take? What websites do you recommend?
What to expect from your doctor
During the physical exam, your doctor will press on various spots around your affected joint to try to determine whether a specific bursa is causing your pain.
Your doctor may also ask you questions, such as:
- When did your pain begin?
- Did it come on suddenly or gradually?
- What kind of work do you do?
- What are your hobbies or recreational activities?
- Does your pain occur or worsen during certain activities, such as kneeling or climbing stairs?
- Have you recently fallen or had another injury?
- What treatments have you tried?
- What effect did those treatments have?
Doctors can often diagnose bursitis based on a medical history and physical exam. If further testing is needed, you might undergo:
- Imaging tests. X-ray images can't positively establish the diagnosis of bursitis, but they can help to exclude other causes of your discomfort. Ultrasound or MRI may be used if your bursitis can't easily be diagnosed by a physical exam alone.
- Lab tests. Your doctor may perform blood tests or an analysis of fluid from the inflamed bursa to pinpoint the cause of your joint inflammation and pain.
Bursitis treatment usually involves conservative measures, such as rest, ice and taking a pain reliever. If conservative measures don't work, treatment may include:
- Medication. If the inflammation in your bursa is caused by an infection, your doctor might prescribe an antibiotic.
- Therapy. Your doctor may recommend physical therapy or exercises to strengthen the muscles in the affected area to ease pain and prevent recurrence.
- Injections. Your doctor may inject a corticosteroid drug into the bursa to relieve inflammation in your shoulder or hip. This treatment generally brings rapid pain relief and, in many cases, one injection is all you need.
- Assistive device. Temporary use of a walking cane or other device will help relieve pressure on the affected area.
- Surgery. Sometimes an inflamed bursa must be surgically drained, but only rarely is surgical removal of the affected bursa necessary.
Measures you can take to relieve the pain of bursitis include:
- Rest and immobilize the affected area
- Apply ice to reduce swelling
- Take an over-the-counter medication, such as ibuprofen (Advil, Motrin IB, others) or naproxen sodium (Aleve, others), to relieve pain and reduce inflammation
- Cushion your knees if you sleep on your side by placing a small pillow between your legs
- Avoid elbow pressure by not leaning or placing your weight on your elbows to rise from a lying position
While not all types of bursitis can be prevented, you can reduce your risk and the severity of flare-ups by changing the way you perform certain tasks. Examples include:
- Using kneeling pads. Use some type of padding to reduce the pressure on your knees if your job or hobby requires a lot of kneeling.
- Lifting properly. Bend your knees when you lift. Failing to do so puts extra stress on the bursae in your hips.
- Wheeling heavy loads. Carrying heavy loads puts stress on the bursae in your shoulders. Use a dolly or a wheeled cart instead.
- Taking frequent breaks. Alternate repetitive tasks with rest or other activities.
- Walking around. Try not to sit in one position too long, especially on hard surfaces, because that puts pressure on the bursae in your hips and buttocks.
- Maintaining a healthy weight. Being overweight places more stress on your joints.
- Exercising. Strengthening your muscles can help protect your affected joint.
- Warming up and stretching before strenuous activities to protect your joints from injury.
