Hi @Graeme Fraser, my hit was way back in 1993. At the time I was young and bulletproof, so I initially chalked the pain up to a strained muscle. Over that first several hours though, the pain just slowly got a bit worse. And indeed, the epicenter really was "deep" in the joint. It was a very different feeling from the normal joint pains I commonly get from my middle-aged body body exposed to exertion.
I did have a bit of a worry a couple of years ago when after a dive I noticed a fairly distinct pain in my right sterno-clavicular joint. Then it occurred to me that I had just spent 25 minutes in deco in a ripping current while hanging on a line (wearing doubles and a stage)...most of that time was spent hanging on with my right hand. It was noticeably sore, but nothing like that deep pain I had felt when I actually got bent. I monitored the pain and sure enough it began subside and completely went away over the next couple of hours. But yeah, I always pay attention to those little aches now.
