Lumbar Symphatetic Block

This medical procedure is an injection that desensitizes branches of nerves in the lower back.  It aids physicians to search and address a list of issues in line with these nerves.  Normally, a number of injections is required to address these issues.

About the Sympathetic Nerves

These sympathetic nerves traverse both sides of the spinal cord. These nerves are related to a long range of functionalities that you don’t deliberately control. These functions consist of circulation, digestion and sweating.


The patient lies down on their stomach (or on the side) while getting ready for the procedure. A medication to relax your nerve is given while the skin and tissue of the back is desensitized using a local anesthetic.

Inserting the Needle

The doctor pushes a needle and meticulously leads it towards the sympathetic nerves. This is made possible by the use of an x-ray device called a “fluoroscope”.

The fluoroscope reveals a video image of the needle’s location. The use of a contrast dye increases the accuracy of locating and validating the location of the needle.

Injecting the Medication

Following the careful validation of the needles exact position, the doctor positions a steroid-anesthetic medication.  This prescription bathes the inflamed nerve roots which will help ease the pain being experienced by the patient. These procedure also manages and reduce the pain and inflammation of the nerves.  Other benefits can be derived from this procedure depending on your condition.

End of Procedure

After the procedure, the needle is withdrawn and the entry point in the skin is cleaned and bandaged. Post procedure monitoring will be done with a few hours, before you are sent home. Most patients after the procedure experience leg numbness and frailty. This is a normal occurrence and can be felt for a few hours. There is also a possibility that you might need additional injections in the future.
