Cracking Joints

Most Likely Causes:
The fluid around a joint contains a variety of gases, such as oxygen and nitrogen. When you crack a joint, you cause the joint to stretch, which rapidly releases gas bubbles that snap, crack, or pop. The cracking sound could also be due to a tendon rubbing across bone.

Less Likely Cause:
If you feel pain each time a joint cracks, it may be a sign of a cartilage or joint problem, such as arthritis.

What to do:
-If the cracking doesn't hurt, don't sweat it.
-If you have pain or swelling, or the joint is red or warm or has limited motion, see a doctor to find out what's going on.
