My sudden, steep learning curve with TFCC reminded me of another piece of anatomy, the intercostal muscles, that I learned about, also as a result of a sports-related injury.
Much like my ignorance of the TFCC, I had no idea what intercostal muscles were, until about six years ago when I injured mine when I was paddling an outrigger canoe. And, like with the TFCC, I learned how important intercostals were, and how I’d been taking them for granted my whole life. So, what are intercostal muscles? They are the muscles between and around your ribs. And once they have been pulled or strained, you are in a world of hurt. You don’t want to sneeze, or cough, or laugh. And there seems to be no way to cure this situation except by discontinuing exercise involving your “core” for 4 to 6 weeks. Do that, and you’ll recover fully. Here’s another picture of intercostal muscles that many people are familiar with, albeit these intercostals are from eine schweine.
