What is that sound or where does it comes from when you move your head and your neck is going “knarr knarr” ( kinda the sound when you walk on dry snow). And why is it there, sometimes?

Question

Right now I have shoulder and neck issues and this sound is making me wonder these questions.

A slight educated guess – I suspect it is due to the joints moving.

You have stuff called ‘synovial fluid’ in your joints that’s basically like oil, sometimes when you ‘crack’ your joints, this is air/gas bubbles popping.

Your joints still can rub against eachother which can cause this noise.
