Ganglion Impar Block in Palm Coast, FL

When pain settles into the tailbone or deep in the pelvis, one small nerve cluster often turns out to be the relay carrying it — and it can be quieted directly.

What it treats

A ganglion impar block targets pain arising from the lowest structures of the spine and pelvis:

It’s typically considered once cushions, activity changes, and physical therapy haven’t resolved the problem, or when the pain is severe enough that waiting isn’t reasonable.

How it works

The sympathetic nervous system runs a chain of nerve clusters, called ganglia, down each side of the spine. Those two chains converge and end in a single fused cluster — the ganglion impar — sitting just in front of the joint where the coccyx meets the sacrum. It carries sympathetic pain signals from the perineum and the lower pelvic structures, and it sits directly against the coccyx, which is why blocking it is an established option for tailbone pain as well as perineal and pelvic pain.

Placing local anesthetic around that ganglion interrupts the signals travelling through it. Because it’s a single small structure in a confined space, and its exact position varies, reaching it accurately is the entire technical challenge — and it can’t be done reliably by feel.

Dr. Manuel López, a board-certified pain management and rehabilitation physician, performs this block under precise image guidance, confirming needle position before any medication is delivered.

What to expect

The block is performed as an outpatient procedure and you return home the same day.

  • Before: you’re positioned face down, and the skin near the tailbone is cleaned and numbed.
  • During: using imaging for continuous guidance, Dr. López advances a thin needle to the front of the sacrococcygeal junction, confirms placement, and delivers the medication. The area is numbed first; most patients report pressure.
  • After: plan for someone to drive you home.

The thing to pay attention to afterward is sitting — the hard chair, the car seat, the moment of standing back up. Whether those change, and by how much, is what tells Dr. López this was the right target.

Is it right for you?

A block along these lines is often considered when:

  • Tailbone pain has persisted despite conservative measures
  • Pain is well localized to the coccyx, perineum, or lower pelvis
  • You need to know whether this pathway is carrying your pain before considering anything more durable

Given the location, Dr. López will review anything affecting infection or bleeding risk, along with any prior surgery or radiation in the pelvic area, since that can change the anatomy and the approach. Bring your full history to the consultation — with this block in particular, the details of what’s been done down there before genuinely matter.

Talk to someone who treats this

Tailbone and pelvic pain get dismissed more often than almost anything else we see. If yours hasn’t been taken seriously, start with a consultation.

Frequently Asked Questions

If your question is not answered here please call or message our office.

It's a single small cluster of sympathetic nerve fibers at the very base of the spine, where the two sympathetic chains running alongside your spine finally meet. Everyone has one, though its exact position varies from person to person — which is part of why it has to be located with imaging rather than by feel.
Not with a block. A block delivers anesthetic, and sometimes a steroid, to interrupt signaling temporarily. If a block reliably relieves your pain but the relief keeps fading, Dr. López may discuss a longer-lasting approach — but that's a separate decision made only after a block has shown the target is correct.
The ganglion sits deep, immediately in front of the sacrococcygeal junction, and is reached under continuous image guidance through a small area of numbed skin near the tailbone. Dr. López will walk you through the positioning before anything begins.
It can. Because this ganglion carries pain signals from the perineum and the lower pelvic structures, it's also used for certain pelvic and cancer-related pain that hasn't responded to other approaches.
