Don't know, my degree is not in medicine or physiology, so take anything I say with a grain of salt.

How long ago was this? Did the scoundrel use fist or some object?

Were you x-rayed at the time to determine if any bones were broken?

Sorry to hear about that. Is the cracking a result or do you use the cracking to alleviate stiffness or pain?

No, being new here, I haven't perused all the threads…...do tell!

It's completely unfair that there are some people who don't crack…for them!

Quite the boutique crack to be sure, I've only popped this one by accident!

That funny long one next to the big toe most often resists cracking –-

that little rascal!

The back definitely - especially after some manual labor or a lot of standing

I try and hold the left side of my body stationary, then twist my right arm around towards the rear. Usually opens up whatever joint is in the chest. Seems like there's a lot of confusion about exactly what joint this is?

underwater is interesting, sounds pretty cool when your head is submerged during the crack

Depends on the joint, my usual refractory period for the digits is about twenty minutes, greater joints like elbows, knees, ankles - 3 hours or more.
