Bursa Injections

Bursa injections can help diagnose the source of pain and provide relief by delivering local anesthetic (numbing medication) and anti-inflammatory steroid medications into specific synovial fluid filled fibrous sacs (bursa), which are adjacent to joints in the body. This procedure may reduce inflammation, resulting in long-term pain relief.

Procedure Preparation

• A technologist or nurse will contact you 24-48 hours prior to your appointment to review medications you are currently taking, especially pain medications and blood thinners, discuss known allergies and your medical history, as well as answer your questions.
  • Contact your doctor before you stop taking any medication.
• Please bring previous imaging study results (MRI, CT, x-rays) such as films, reports, or CD-ROMs, if available.
• You will need a driver for your appointment. If you are unable to drive or arrange transportation, call us for assistance.
• Please notify a member of your doctor’s staff if you are nursing or if there is a chance you may be pregnant.

During the Procedure – What to Expect

• Using a thin needle and x-ray-guidance (fluoroscopy), a radiologist will inject contrast (x-ray dye) into or adjacent to the Bursa thought to be causing your pain. This will ensure correct placement of the needle for the procedure.
• X-rays will be taken and a combination of an anti-inflammatory (steroid) and anesthetic (numbing) medications are then injected for pain relief.
• You will remain awake during the 10-20 minute procedure, and may experience some slight pressure or discomfort during the injection.
• Please inform the radiologist how it differs from your usual symptoms.
• You will be asked to wait 30-40 minutes after your procedure before leaving.

After the Procedure – What to Expect

• You may experience numbness and/or relief from your symptoms for up to six hours after the injection.
• Your usual symptoms may then return and may possibly be worse than usual for a day or two.
• The beneficial effects of the steroids usually require 2-3 days to take hold, but may take as long as 5-7 days. If there is no change in your symptoms after a week, your doctor may want to investigate other possible sources for your pain.
• If an initial injection provided a certain amount of relief, a second injection might strengthen the pain relief effect. Also, if your pain subsides, but begins to return weeks or months later, additional injections – up to four a year – are possible.
• Keep track of how long relief lasts and report it to your physician. If there is no change in the pain, then investigation can be focused on other possible sources of your pain. In either case, the information is useful to the doctor who referred you for this procedure.

Possible Side Effects

• Steroid medications may cause facial flushing, occasional low-grade fevers, hiccups, insomnia, headaches, water retention, increased appetite, increased heart rate, and abdominal cramping or bloating.
• These side effects occur in only about 5% of patients and commonly disappear within 1-3 days after the injection.
