Lumbar sympathetic block

This procedure uses an injection to numb nerves in your lower back. By numbing the nerves, the doctors can identify problems with the nerves.

The sympathetic nerves go alone your spine and control body processes like circulation and digestion.

After numbing your skin, your doctor will use an x-ray to position a needle in the proper place on your back. The doctor will inject the medication, which can reduce inflammation and pain in the nerves.

You may have leg numbness or weakness for a few hours after the injection.
