I believe it is a bit of both. Cracking or rather streching the joints will create tense liagments which will cause uneasiness in the joints until you click them again and again and….
However, you are also much more likely to click joints when you are in physiological stress. The last 2 days I had high stress like that and threw my resolve to reduce cracking overboard. The worries I had were overshadowing the Joint cracking ones for this time so I couldn't bother being annoyed by them too.
It is kinda silly, but that's how it works I guess.
When you have cracked your joints for many years, llike I have, it will take a very long time to totally stop if ever.
