What is the purpose of diagnostic nerve blocks before the RF procedure?

The purpose of diagnostic nerve blocks before a radiofrequency (RF) procedure is primarily to determine the location and accuracy of the target nerve. By administering a nerve block, a clinician can assess whether the pain relief achieved corresponds with the area supplied by the targeted nerve. This helps confirm that the correct nerve is selected for the RF procedure, ensuring that the treatment will be effective.

Additionally, by observing how the patient responds to the nerve block, practitioners can gather essential information about the pain's source and the likelihood that an RF procedure would provide lasting relief. This is a crucial step in the treatment process, as it enhances both the precision of the procedure and improves patient outcomes.
