Hi /fit/I just started experiencing a crackling, rice-crispy-esque noise coming from the back of my neck. This will sometimes occur when I move my neck, but not always. I tried researching this through google/various medical websites, but they all seemed to point me in the direction of arthritis (which I find to be unlikely because I'm 20). I had a back injury from work a few months ago that I'm still recovering from, but it was in an entirely different location than this, and this is the first day I've heard this noise.Any thoughts?
