Weird thing that I've observed. I'd never suggest it. I've met several masochists (the m in bdsm) who live with chronic pain and participate in the kink community because, as far as I can understand, it's a way to reframe the chronic pain that they experience. Or maybe, it's like getting out of a boiling hot car into the relative cool of a blazing summer day. The people I've met under these circumstances have had extreme pain tolerance, to the point where their sadists tread a fine line of giving them enough without doing damage. I know that many masochists experience (and seek) a significant endorphin response, and I've long wondered if exercising that somehow increases their endorphin production capacity -- and if that would provide an enduring benefit to those who live with chronic pain.
