What is it?
A Lumbar Sympathetic Plexus Block is a block that can be used to relief lower leg pains from: CRPS, Vascular insufficiency, peripheral neuropathy, herpes zoster infection (Shingles) involving the legs. The lumbar sympathetic nerves are located on both sides of your spin, in your lower back.
How Long does the Procedure Take?
Lumbar sympathetic plexus block is a minimally invasive procedure that takes less than 30 minutes to perform. The procedure is typically done under Fluoroscopic guidance where local anesthetic and steroid are injected.
What are the Expected Results?
The relief from a positive diagnostic block is almost immediate, as the effects of the local anesthetic should typically be felt before the patient even leaves the office. The local anesthetic will wear off in just a few hours and the pain may return, which is normal. Longer term relief usually begins in 2-3 days, once the steroid begins to work. Usually patients need a series of injections to continue the pain relief. If the pain returns, you can have block every few months. Other options to consider for longer term relief may include, RFA of the lumbar sympathetic plexus or consideration of Spinal cord stimulator.
