“What causes bones to crack?”
I'm 20 years old and male, and I've realized that I have extremely creaky bones and joints, which causes them to crack every so often. What's causing this?

Your bones are not cracking. If they were, they would be fractured and require splinting, casting, or surgery. Your joints are likely what are cracking. It is likely due to the normal flow of fluid within the joints that causes the noise. However, if the cracking is associated with pain or swelling or loss of movement, you should see an orthopedic surgeon as soon as possible to find out what is wrong.

"Cracking joints" (such as cracking your knuckles) is actually the release of gas (nitrous oxide) from the joint capsule as it is being stretched. It may also come from the snap or pop of a tendon or ligament around the joint. As long as its not painful and not associated with any other symptoms (instability, locking, catching), it's generally benign and nothing to worry about.
