Multiple Nerve Block injections are performed for diagnostic and therapeutic purposes in chronic pain management.
Simple nerve blocks can be performed in the office with local anesthetics and steroids without any sedation, provided that the patient does not display a high level of anxiety, such as the oxipital nerve block for headaches. Other blocks may require fluoroscopic x-ray guidance like sleeve root injections, such as selective nerve root blocks for sciatica pain.
Theoretically, the nerve block can be performed at any part of the body, depending upon the nerve pathway involved in generating the pain. Most commonly used blocks are as follows
If the patient is undergoing a diagnostic or prognostic block, it is important to report the treating physician accurately, the duration and extent of pain relief. Based on the patient’s response, the further treatment plan will be recommended like surgical intervention or nerve rhizotomy.
The therapeutic nerve block may take a couple of days to take effect before the patient notices any improvement. It is because the steroids used in the therapeutic blocks may take up to 72 hours to take effect and reduce inflammation.
