# Effective Pain Management in Polyarteritis Nodosa (PAN) Utilizing Lumbar Sympathetic Blocks: A Case Report

## TL;DR

A 39-year-old man with polyarteritis nodosa found significant pain relief through lumbar sympathetic blocks, a treatment not previously reported for this condition.

## Contribution

This is the first report demonstrating the efficacy of lumbar sympathetic blocks for PAN-associated pain.

## Key findings

- Two lumbar sympathetic blocks reduced the patient's leg pain by over 70%.
- Pain levels dropped from NRS 9-10 to NRS 3 over three months.
- The treatment provided sustained pain relief unresponsive to oral medications.

## Abstract

We presented a 39-year-old man with polyarteritis nodosa (PAN) experienced significant leg pain unresponsive to oral medications.

Two sequential lumbar sympathetic blocks with ropivacaine and triamcinolone resulted in over 70% pain reduction (NRS 9-10 to NRS 3) over a three-month follow-up period.

To our knowledge, this is the first report showing the efficacy of lumbar sympathetic block in controlling PAN-associated pain.
