The Body’s Wiring: Understanding Nerve Injuries

Nerves are the body’s communication system—carrying signals that allow you to move, feel, and react. But what happens when that system is disrupted? In this episode, we explore the fascinating world of nerve injuries, breaking down how and why they occur, and what it means when those vital signals are slowed, damaged, or completely lost.

Using clear, real-life examples, we walk through the three main types of nerve injuries—from mild “stunned” nerves (neuropraxia), to more serious internal damage (axonotmesis), to complete nerve disruption (neurotmesis). You’ll learn how these injuries can lead to symptoms like numbness, tingling, weakness, or loss of function, and why recovery can range from a few days to many months—or even require surgery in severe cases.

We also explain how nerves are structured, how doctors diagnose these injuries, and what recovery really looks like—including the surprising fact that nerves regrow very slowly. Whether you’re an athlete, a patient, or just curious about how your body works, this episode offers an engaging and easy-to-understand guide to one of the body’s most important systems.

This podcast is based on trusted, patient-friendly information from the free, peer-reviewed website of the non-profit OrthoEducation, available at OrthoEducation.com, dedicated to helping people better understand musculoskeletal conditions.
