Facet joint injection is done in a hospital, a surgery center, or a health care provider's office. You’ll be asked to fill out some forms, including a consent form. You may also be examined.
During the procedure
You may be given medicine to help you relax. You will lie on an exam table on your stomach. During your treatment:
-
The skin over the injection site is cleaned. A medicine (local anesthetic) is used to numb the skin.
-
X-ray imaging (fluoroscopy) will be used so the health care provider can see exactly where to inject the medicine into your spine. A contrast dye may also be injected into the affected area.
-
The injection is given. It may contain a local anesthetic to numb the region around the joint, medicine that eases inflammation (steroids), or both. Once the needle is removed, pressure will be applied to prevent any bleeding. The opening of the skin will be covered with a bandage.
After the procedure
You may be taken to an observation area for several hours then released to go home. Have a friend or family member drive you. The local anesthetic wears off in a few hours. You may feel sore for a few days before the steroid begins to take effect. This is normal. Your health care provider may recommend cold packs to the injection site. They may prescribe pain medicines as needed. Take it easy and stay away from strenuous activity or driving for 24 hours, or as directed by your provider. Ask your provider when it’s OK to go back to work.
