Of course.

My often hourly - sometimes twice an hour cracks include:

Ankles, toes.
Knees.
Lower back.
Elbows,
Wrists,
All joints beyond the wrist till the fingertips.

The hands and ankles get the worst of it though! While working I'm always cracking them, its like a drug!

I love cracking my phalanges on my hands!! Those last little joints on the edge of your fingers. Grab the tips with the plam facing down, and twist quickly in a jerking motion but without too much force.

You'll here a slight click and a feeling of extra relief after having cracked everything else in the hand.

It like a cherry on top of a chocolate pie!

Works best on the middle fingers. Not that I use it much for anything else!
