Why do my hip bones crack?

Question

Im not quite sure its my hip, but its probably around tail bone region. Whenever i lay down flat on my bed or something and squeeze my butt cheeks together, it cracks various times. It feels really relieving though. Could it be bad for me?

Answer 1

you are probably moving your back into alignment, and in the process, popping a few trapped air bubbles along your spine.

Answer 2

lower back, just slightly above your tailbone is cracking, mine does that too. what you should really be concerned with is when your ankles crack. there's something to think about.
