179: Nerve Pain: Stop Blaming Compression (with Whitney Lowe & Til Luchau)

🎙 Nerve Pain: Stop Blaming Compression (with Whitney Lowe & Til Luchau)

Ask almost any manual therapist what they learned about nerves in school, and you get some version of the same answer: not much.

Most of us were handed the wiring model. A nerve is a cable, it carries a signal, and there are two ways it goes wrong — something presses on it, or something pulls on it. It's a tidy picture, it's most of what our field has run on for decades, and it leaves out nearly everything that makes a nerve a nerve.

Whitney and Til go under the sheath. A peripheral nerve turns out to be a living organ with its own blood supply, its own nerve supply, a fascial architecture that mirrors muscle, and a slow river of axoplasm moving proteins the length of an axon that may run three feet from your sacrum to your big toe. Once you see it that way, the clinical picture changes: the first thing a little compression does isn't block a signal, it stalls venous return, and the chemistry that follows is a big part of what your client actually feels.

They get practical about what that means on the table — why there's an argument for getting on nerve problems sooner rather than waiting and seeing, why tensioners make better tests than treatments, why freeing the neighborhood usually beats going after the nerve itself, and why nerves respond to whispers rather than shouting. Along the way: fat wallet syndrome, updated for the age of the back-pocket phone; a rat pulling a lever for food, and the gentle hands-on work that kept it from developing nerve fibrosis; an enzyme sequestered since fetal development that can cause excruciating back pain while leaking out of a disc injury that may barely show up on imaging; a young Whitney in an Atlanta medical bookstore, broke, deciding to spring for a blue book called Mobilisation of the Nervous System; and a likely explanation for why your client feels it downstream of the problem.

✨ We talk about:- Why nerves got so little airtime in our training — and why the field is expanding into them now- Nerves as living organs: endoneurium, perineurium, epineurium, and why the architecture parallels muscle- Vasa nervorum and nervi nervorum — a nerve's own circulation, and its own sensation- The pressure sequence: venous flow stalls first, then arterial, then intraneural — and the "toxic soup" that follows- Neurapraxia, axonotmesis, neurotmesis — and why a damaged axon regrows at roughly a millimeter a day, about an inch a month- The argument for early
