You will not be able to drive for 12 hours after the injection. It's common to experience mild pain at the injection site for 24 to 48 hours. As mentioned, you should not drive on the day of the injection into the facet joint. If your doctor used sedation, do not drive for at least 24 hours after the injection.
Facet joint blocks are usually ordered for patients who have pain mainly in the back as a result of arthritic changes in facet joints or for patients who have mechanical low back pain. Injecting into the facet joint reduces pain in the small joints at the back of the spine, between the vertebrae. You're more likely to notice faster relief if the joints where the injection was given were the main source of pain. If the injection does not relieve pain, it may be because the injection did not reach the source of the pain or because the pain is not caused by facet joints.
It involves injecting medications close to the branches of the medial nerves, which supply sensory information to facet joints. A facet joint injection is a procedure in which analgesic and anti-inflammatory medications are injected into facet joints to reduce pain. A lumbar facet joint block is an injection of local anesthetic (numbing medication) into one or more of the small joints located along each vertebra, on both sides of the spine, in the lower back. If the injection into the facet joint is successful, you should expect to experience pain relief for several months.
If the medication is injected directly into the joint, the procedure is called facet intra-articular injection or simply injection into the facet joint. Facet joints are a pair of small joints located at the back of the spine, between each of the vertebrae.
