Endometriosis and Sciatica: Pioneering Research on Nerve Entrapment, Vascular Compression, and Surgical Solutions

In this episode, Dr. Nicholas Fogelson and Dr. Shanti Mohling dive deep into the complex overlap between endometriosis and nerve-related pelvic pain. They discuss a pivotal paper by Dr. Marc Possover on laparoscopic treatment for endometriosis and vascular entrapment of the sacral plexus — groundbreaking work that opened new paths for addressing sciatica caused by pelvic disease. The conversation explores how nerve irritation and compression can manifest, why menstrual cycle patterns matter, and how careful patient selection guides surgical decisions. If you or someone you know has unexplained sciatic or pelvic pain that worsens cyclically, this episode is essential listening.
