The destruction (also called ablation) of nerves is a method that may be used to reduce certain kinds of chronic pain by preventing the transmission of pain signals.
This procedure is an injection of an anesthetic that is delivered to a specific nerve to relieve pain. We may also use nerve blocks as a diagnostic tool to determine the source of your pain.
A nerve block is an injection of anesthetic on or near the nerve/pain receptor connected to a specific nerve or joint. The procedure is used as a diagnostic test to determine if the pain is actually coming from the nerve or joint. Nerve blocks can happen in the following areas:
If you have pain stemming from a joint or peripheral nerve, then you may benefit from a nerve block injection. Typically, the procedure is recommended for those who do not respond to other conservative treatments, such as oral anti-inflammatory medication, rest, or physical therapy.
If a steroid joint injection confirms that the joint is the likely source of pain, then a diagnostic nerve block test may be recommended to determine if a radiofrequency ablation would provide more lasting pain relief.
A nerve block injection is done using fluoroscopic (x-ray) guidance and should NOT be performed on people who have an infection, are pregnant, or have bleeding problems.
