Nobody is getting any younger, which is too bad. Muscle cramping...fatigue...stiffness... you'll be dealing with it more and more. “It's probably nothing,” you tell yourself. But what if it's not? Every once in a while, you might come across a case of myotonia. And you won't want to miss it. This week on BrainWaves, Dr. Noah Levinson provides a brief overview of myotonia and the conditions that are associated with it.

Produced by James E Siegler. Music courtesy of Yshwa, Steve Combs, MMFFF, and Scott Holmes. Sound effects by Mike Koenig and Daniel Simion.
