You may start to notice an improvement in pain 2 to 5 days after the injection. If you don't notice improvement within 10 days after the injection, it's unlikely to occur. You can take your regular medications after the procedure, but try to limit pain medications for the first 4 to 6 hours after the procedure. The steroid in a facet joint injection does not start working right away.
It usually takes two to seven days for patients to begin to experience a reduction in pain. However, immediately after the injection, there will be some relief thanks to the local anesthetic used. The beneficial effects of steroids generally require 2 to 3 days to be effective; in some cases, they may take up to 5-7 days. If your symptoms don't change after a week, see your doctor to investigate other possible causes of your pain.
Usually, facet injections start to work in 3 or 4 days, although the steroid can take up to 7 days to start working. Facet injection is a minimally invasive procedure that can temporarily relieve joint or nerve pain caused by inflammation of the facet joints. First, it can be used as a diagnostic test to see if the pain really comes from facet joints. In some cases, medical imaging tests, such as MRIs or CT scans, may not detect inflammation or injury to the facet joint, so your doctor may suggest an injection to rule out that the facet joint is the source of pain.
A facet joint injection is a procedure that identifies the source of irritation in the small joints in each segment of the spinal column. Using a fine needle and radiographic guide (fluoroscopy), the doctor will inject a contrast medium (X-ray dye) into or near the facet joint that is thought to be causing the pain. If you experience chronic back or neck pain that has lasted more than six weeks and other interventions haven't helped, your doctor may suggest that you try facet joint injections to try to relieve the pain. Facet joint injections in the lower back or lower back are usually helpful when pain involves lower back pain that radiates down the lower back and slightly down the back of the upper thighs and buttocks.
This is a good way to strengthen your back muscles and determine if the injection was given into the correct facet joint. When one or more facet joints deteriorate for any reason, the pain may radiate to other areas of the body. If an initial injection provided some degree of relief, a second injection could reinforce the pain-relieving effect (known as “build-up”). Facet joint pain can be caused by numerous factors, including arthritis, degenerative disc disease, falls, and car accidents.
The doctor will spend considerable time evaluating the patient's condition before administering an injection into the lumbar facet joint or an injection into the cervical facet joint. As explained by the North American Spine Society, if you experience any local or throbbing pain (such as in the legs), your doctor may suggest an injection into the facet joint as a way to diagnose pain or see if your pain improves. They protrude from the vertebrae and meet the facet joints of the vertebra, either below or above them. If the injection effectively blocked your pain, but only for a short time, your doctor may recommend additional injections.
