Lumbar Sympathetic Block
Targeted Injection for Persistent Lower Body Pain
A Lumbar Sympathetic Block is a specialized injection that helps diagnose and treat pain traveling to the lower back or legs. This treatment targets the sympathetic nerves along the spine that may be contributing to persistent discomfort. At iMsk & Spine Group, lumbar blocks are carefully performed by experienced pain specialists, offering patients measurable relief and improved mobility.
What Is a Lumbar Sympathetic Block?
This injection delivers medication near the sympathetic nerve chain in the lower spine. By interrupting unusual nerve signals, the treatment can reduce inflammation, calm nerve irritation, and relieve pain that radiates into the lower extremities. In some cases, it also helps determine whether sympathetic nerves are the primary source of pain.
Why It Helps
The sympathetic nervous system can trigger chronic pain even when the original injury or irritation has improved. By blocking these nerve signals temporarily, patients often experience relief that allows improved movement and daily activity, as well as clearer direction for ongoing treatment.
Conditions It Helps Treat
A Lumbar Sympathetic Block may be recommended for:
- Chronic lower back pain
- Pain radiating into the legs
- Complex Regional Pain Syndrome (CRPS)
- Sympathetically maintained pain
How Treatment Works
This procedure is performed under image guidance to ensure safe and accurate medication placement.
A typical session includes:
- Local numbing
- Targeted anesthetic or anti-inflammatory medication
- Short monitoring period
- Return home the same day
Relief may develop quickly or gradually based on the condition being treated.
