This information with help you understand bursitis, including causes, diagnosis and treatment.
Bursitis is a painful condition caused by the swelling of a small sac of fluid filled pads called bursae (see Figure 1).

- Pain, stiffness, or discomfort around your elbow, hip, knee, shoulder, or other joints. You may feel this while your moving or at rest.
- Loss of movement due to pain and inflammation.
- Swelling, although this is mostly seen in the elbow or foot
Your doctor can usually make a diagnosis based on your symptoms and a physical exam. He or she may order blood work and x-ray exams to rule out other possible problems. If there are signs of infection, you may need to have a biopsy. A biopsy involves removing a small amount of bursa fluid with a needle.
Your treatment may include rest, medications, ice or heat, occupational or physical therapy, or steroid injections. Your healthcare team will make treatment recommendations based on your symptoms.
The goal of treatment is to:
- Reduce pain and inflammation
- Maintain the use of your joint
- Prevent a return of bursitis
Rest your joints and avoid activities that cause pain and worsen your symptoms.
You may be prescribed nonsteroidal anti-inflammatory drugs (NSAIDS), such as:
NSAIDS may have side effects. Talk to your doctor before taking NSAIDs.
Ice or heat
Your doctor or nurse may tell you to ice or heat your joints. Apply ice or heat for 20 minutes every 4 to 6 hours.
When using heat you should:
- Fill a water bottle with warm, not hot water.
- Do not leave a heating pad on your joints for more than 20 minutes at a time.
Your doctor may refer you to an occupational or physical therapist. Your therapist will:
- Show you exercises to strengthen your joints
- Tell you how to protect your joint, which will promote healing and prevent a recurrence
- Provide an ultrasound, massage, or other therapies
If your symptoms continue or get worse, your doctor may inject a steroid into the area surrounding your joint. This will help to decrease inflammation and pain.
