A facet block temporarily relieves pain caused by the nerves of the facet joints.
A facet block involves injecting drugs (cortisone and lidocaine) into the facet joints of the spine (which can be found in the cervical, thoracic or lumbar region). A maximum of 4 sites can be injected per appointment. If you need injections at more than 4 sites, you will have to get a second appointment two weeks later.
Some patients need 2 to 3 different injections (also called “infiltrations”) to get relief. You can get up to a maximum of 3 infiltrations per year for the same site. You must wait three months for an infiltration at the same site and two weeks for a different site.
Notify your doctor or the technologist before your treatment if you have allergies or if you are pregnant.
You do not need to have someone accompany you to the treatment. Most people can drive after getting the injection. However, the radiologist will let you know if he or she believes you won’t be able to drive.
You can go back to work after your treatment depending on the nature of your job. Ask your doctor before your appointment.
