Is it bad if your bones crack a lot?
Creaking and snapping joints might be annoying, but they usually are nothing to worry about, says orthopedic surgeon Kim L. Stearns, MD. “It's a normal, common occurrence,” he says. But if the constant cracking is coupled with consistent pain or swelling, that can be a sign that something is wrong.
What are you lacking when your bones crack?
Cracking knees and joints is sometimes caused by vitamin D and calcium deficiency, and sometimes dehydration. Our bodies need to be hydrated so collagen can form and lubricate around our joints.
