What are Facet Injections? How do they work?

This procedure where medication is directly applied to facet joints, usually along the spine. Inflammation and swelling within these joints can cause major discomfort, and this injection aims to lessen the pain felt by irritated joints.

Benefits from an Facet Injection

This procedure is very quick, and allows patients to quickly return to normal daily activity. Patients who need injections at multiple locations can schedule them within a short time of each other to experience total relief. Patients with reoccurring inflammation, such as those with arthritis, can receive these injections within the same problem joints up to 3 times a year.

When will I see results?

When injected, the anesthetic that is mixed with the rest of the treatment relieves pain immediately, but this numbness dissipates within 24 hours. These injections should completely relieve pain within 3 days to a week.


Using guidance equipment your doctor will determine the facets best suited to receive an injection. The chosen area is then sterilized and a local anesthetic given to make the patient more comfortable. The medication is injected and gives the patient immediate pain relief, although this wanes and long-term effects are expected to show within the first week after the procedure.

Risk Factors

There is a risk of complication with any medical procedure. Take time to discuss treatment options and any questions you may have with your physician, before agreeing with a procedure.
