What Is a Diagnostic Nerve Block and How Does It Work?
A diagnostic nerve block is a procedure used to identify the exact source of pain in the body. It involves the injection of a local anesthetic or medication near a specific nerve or group of nerves suspected to be responsible for the pain. By temporarily numbing the nerve, the procedure allows doctors to observe how the patient’s pain responds. If the pain subsides after the nerve is blocked, it confirms that the specific nerve or nerve root is the source of the discomfort. This helps healthcare providers accurately diagnose the condition and target treatments more effectively.
Diagnostic nerve blocks are commonly used for a variety of pain conditions, such as joint, back, or neck pain, as well as conditions involving nerve compression. The procedure is minimally invasive, and the patient can typically return to normal activities shortly after. While the effects of the nerve block are temporary, it provides valuable insights into the cause of the pain. Based on the results, healthcare providers can develop a more tailored treatment plan to address the underlying issue and relieve pain more effectively.
