Lumbar Sympathetic Block

Functions of the Sympathetic Nerves

Sympathetic nerves located in the lower spine control basic functions such as regulating blood flow. They also carry pain signals from tissues to the spinal cord.

What is a Lumbar Sympathetic Block?

A lumbar sympathetic block is an injection of a local anesthetic and steroid that is injected into or around the sympathetic nerves to block the transmission of pain impulses from the legs or lower back, thereby relieving pain.

Indications for a Lumbar Sympathetic Block

The lumbar sympathetic block is usually indicated as a treatment for conditions such as:

  • Reflex sympathetic dystrophy (pain and dysfunction of an extremity/CRPS)
  • Herpes zoster infection
  • Vascular insufficiency (impaired blood flow)
  • Peripheral neuropathy (nerve damage)

You are contraindicated for this procedure if you are allergic to the medications being injected, are taking blood thinning medications, have an active infection, or you have diabetes or a heart disorder.

Lumbar Sympathetic Block Procedure

The lumbar sympathetic block is performed under local anesthesia and sedation, in an outpatient setting. You will lie flat on your stomach. Your doctor will numb the area of your lower back to be treated. With the help of live X-rays, your doctor will insert a needle into your back. A dye is then injected to check the correct path of the medication. When this is confirmed, the steroid medication and anesthetic are injected into the target site. The entire procedure usually takes less than 30 minutes.

What to Expect after Lumbar Sympathetic Block

After the procedure, you may feel warmth in your lower back and your legs may feel numb or weak. You may have pain relief immediately after the injection, but pain may return after a few hours as the anesthesia wears off. Relief from the medication is observed in 2 to 3 days, as the steroid begins to work. Most often you will need 2 to 10 injections at regular intervals to get continued pain relief.

Risks and Complications of Lumbar Sympathetic Block

This procedure is usually safe and the risks are rare. However, as with most therapeutic procedures, a lumbar sympathetic block may be associated with certain side effects such as temporary pain or soreness at the site of injection, bleeding, and infection.

Dr. Iqbal is the best pain management doctor I have ever had and will have. She does her homework first which I think makes the difference in diagnosis. She is the total package, a very smart and beautiful doctor, wife, and mother. Hand on Bible she changed my life, and I will forever be in debt to her. I can't say thank you enough. I appreciate her staff; they are all awesome as well. I laughed and cried in her office, but her smile and staff always made me feel welcome like part of their family. I would and will drive across country to see her. The referral to a new knee surgeon to fix a bad knee replacement was the best. I got a new knee, and it has been a huge blessing as well. Thank you, Dr. Iqbal and staff you all are 5 stars, in my life.

I visited this facility in January for severe back pain I was experiencing. The whole ordeal from beginning to end was amazing. I wish I had known about this place years ago before suffering from so much pain. Dr. Mehreen Iqbal, her assistant Michealle Dooley and their staff is the best. I had a procedure done on 1/17/24 and I no longer suffer from back pain and I'm able to walk again. I highly recommend this facility, 10 Stars!!!

My PCP recommended Dr. Mehreen and she was wonderful through out the entire injection process. She took her time explaining everything and was patient through out the process. In my opinion, she is the best pain management doc around.
