Considering that doctors may recommend facet joint injections as often as three times a year, a positive result can be expected to last about four months. When it comes to the duration of pain relief that patients may experience due to a facet block, there really isn't a concrete answer. However, when the source of the pain is located, patients usually feel immediate relief due to local anesthesia. The effect of this medication will wear off after a few hours, and it may take two to seven days before patients experience the lasting effects.
The amount of time you experience pain relief will vary. For some people, relief may only last for a few weeks. Others may notice that the pain has gone away for months or even years. If the pain recurs, you can always get additional injections.
The relief from Facet injections varies widely and can range from weeks to two months. Facet joint pain is usually due to arthritis or joint degeneration, and is described as pain that remains along the spine and worsens when sitting, standing, or driving for a long time. Facet joints are small joints at the back of the spine and are found at all levels, from the lower back to the neck. If you suffer from chronic back or neck pain, you may be a good candidate for facet joint injections.
However, if the first injection into the facet joint does not relieve the patient's pain, the injection should not be repeated. Before a facet joint injection, you may be given a diagnostic injection called a medial branch block near a nerve that comes out of the facet joint. It's important to know what to expect after receiving facet joint injections so you can be prepared for the recovery process.
