What is a bursa?
A bursa is a small fluid-filled sac that acts as a cushion between bones, tendons, and/or muscles. It allows free movements by reducing friction between the bones. Bursa injections can deliver local anesthetic and anti-inflammatory steroid medications into specific bursa, thereby reducing inflammation and providing long-term pain relief.
How is the procedure performed?
Your physician will insert a thin needle into the bursa specific for your pain, and under the guidance of x-ray, an anaesthetic and anti-inflammatory medications will be injected.
What should I expect after the procedure?
You may or may not experience numbness and pain relief immediately after the injection due to the local anesthetic. When the local anesthetic wears off, your symptoms may return. You may start noticing pain relief after a couple of days from the steroid. The effects of steroids may, however, take as long as 5-7 days to take hold. If you don’t feel the difference in your pain symptoms after a week, your physician may want to check for other possible sources of your pain or give you a second injection.
Possible side effects and risks
Some of the rare side effects of steroid medications that occur in about 5% of patients include fevers, insomnia, headaches, water retention, increased appetite, increased heart rate, and abdominal cramping or bloating.
