Lumbar Sympathetic Injection Information

What is the Lumbar Sympathetic Chain?
The lumbar sympathetic chain carries many pain fibers from the lower extremity.� It is involved in some pain conditions such as Complex Regional Pain Syndrome (formerly known as Reflex Sympathetic Dystrophy).� The Lumbar Sympathetic chain runs along the anterior and lateral aspect of the lumbar vertebrae.� This can be targeted for injection at a number of different levels; the procedure is most often performed at the L3 or L4 vertebrae.� Your doctor will tell you if there is a significant sympathetic component to your pain and you are a candidate for an injection of the sympathetic chain.��

How is a Lumbar Sympathetic Injection performed?
It is a relatively simple procedure in which the physician uses fluoroscopic guidance to place a small needle along the Lumbar Sympathetic chain.� You will need to lie still on your stomach for a few minutes so the procedure can be performed.� After you are brought into the room, your skin will be cleaned thoroughly.� Next, the physician will numb a small area of skin that may sting for a few seconds. The physician will use x-ray guidance to direct a small needle into the ideal position along the Sympathetic chain.� After the needle is in the proper location, a small amount of contrast dye is injected to ensure the injection will flow as desired along the sympathetic chain.� The procedure will take a few minutes.� You may feel temporary discomfort as the needle passes through muscle.� Relief from the injection may wane after several hours to a few days and repeat injections are often necessary.

What should I do after the procedure?
No driving for eight hours. Do not apply heat to your back for the first 24 hours after the procedure.� The injections should be done in conjunction with a physical therapy program.� Appointments for physical therapy should be made on the days of the procedure or the day following the procedure.� Speak to your physician if you have questions about the timing of therapy appointments in relation to the injections.

General Pre/Post Instructions

These medicines may be re-started the day after the procedure. You may take your regular pain medicine as needed before/after the procedure.
