@Hazuki:

My ankles sometimes just crack when I walk. My mom tease me saying I'm old and sound like popcorn. lol Maybe try cranking other joints so that you aren't focused on just one? I have a bit of ocd or so the headshrink told me and I went there one day then that was it. lol ><

yeah i think a lot of crackers have OCD, its come up on this forum before
