Pop goes my jaw

Since I was young, I've had the ability to crack various joints on my body. It started with the big knuckles on my hands in fifth grade.

Now I can pop:
— All five big knuckles on each hand (10)
— The four medium knuckles on my fingers on each hand (8)
— Both wrists (2)
— Both elbows at times (2)
— All 10 toes (10)
— My neck (2)
— My back (2)
— My chest (1) — this started a couple years back when I was doing heavier bench pressing

And now the left side of my jaw. It's the weirdest sensation. I'm not sure if anyone else can hear it, but because it's right next to my ear, it's loud to me.

Needless to say, I don't think this is a good thing. When my chest started popping, I went to several doctors and they told me it was normal. I don't think my jaw's supposed to pop, however.

The Internet certainly doesn't help calm me down with all the scary information out there.

But I'm going to schedule a physical after I get back from Boston. Hopefully it's something minor and can be corrected.
