For anyone who’s ever been told their spine is “degenerating” or that they’re a millimeter from paralysis, the fear can feel as debilitating as the condition itself. In this episode, Dr. Brent sits down with his own neurosurgeon, Dr. Allan Levi — Chairman of Neurological Surgery at the University of Miami Miller School of Medicine and Chief of Neurosurgery at Jackson Memorial Hospital — for a full-disclosure conversation about lumbar spinal stenosis, one year after Dr. Levi performed the surgery that gave Dr. Brent his leg back.
Dr. Levi breaks down what stenosis actually is, why imaging findings so often don’t match a patient’s symptoms, and why some people walk around with “severe” degenerative changes on MRI and no pain at all. Together they trace the full continuum of care, from physical therapy and diagnostic epidural injections to the decision points around laminectomy versus fusion, and what recovery really looks like at each stage. It’s a candid, myth-busting conversation for anyone facing a stenosis diagnosis or supporting a patient through one.

Dr. Brent walks through his own confusing symptoms across his knee, foot, ankle, and hip before his stenosis diagnosis came into focus.
10:15 — The Diagnostic Epidural
Dr. Brent describes how an epidural injection helped pinpoint which spinal level was actually causing his symptoms.
11:53 — Stability and Individual Variation
Dr. Levi notes that every patient’s case is different, with some having instability associated with their stenosis.

Dr. Brent asks Dr. Levi to walk through how he determines whether a patient’s spine is stable or unstable.
19:40 — What a Laminectomy Involves
Dr. Levi describes the standard decompression procedure and how it creates more room for compressed nerve roots.
21:16 — When Fusion Becomes Necessary
Dr. Levi explains how spondylolisthesis (vertebral slip) often requires fusion alongside decompression.

35:34 — Beware Surgical Fear Tactics
Dr. Levi cautions against surgeons who claim surgery is needed immediately to avoid paralysis.
36:00 — The Risk of Waiting Too Long
Dr. Levi and Dr. Brent discuss how delaying necessary surgery for years can lead to worse outcomes from chronic nerve compression.
36:41 — Neuroplastic Pain After Long Delays
