Thanks for the reply, and question. No, I do not remember anything happening to my neck, as did in your case.
Oddly, I think what is happening to me might have a good side to it. Over time, my posture is actually improving. Plus, as far as I can tell, the nature of the cracking has changed over time. It seems lots more "effective" now, and deeper, than it did at first. But the progress is incredibly slow. It takes LOTS of cracking to get anywhere in this process.
People in my age category tend to start slumping over, and some of that involves the actual bone structure, discs, and ligaments and so on. In my case the process is evidently going the other direction. So, I am willing to consider this a very good development. But I wouldn't mind it finishing up rather than just continuing indefinitely.
My point is that the clicking may have started on its own anyway, in your case, since it certainly did in mine. My point is also that the cracking might indicate the start of a really good thing, such as a beneficial change in structure. I seem to have several clear health benefits coming from this – and I could give details about those too, if anyone is interested.
Do you (dj) have a slouching posture? And is it changing. along with the joint cracking? If not, then your situation might not be the same as mine -- or it might be a very early stage of what I have going on.
I will be interested in your response, and ideas.
