Is cracking your knuckles bad?

The short answer, NO.

The long answer is chronic knuckle cracking can lead to joint laxity, meaning loose joints. This can set you up for hand sprains however. It does not give your arthritis, nor does it give you large knuckles.

So why do they 'crack' or 'pop'?

The cracking noise you hear is called a cavitation. A cavitation is the technical term for the release of a gas bubble inside a joint. To be more specific, it is a release of Co2 and nitrogen within the synovial fluid inside of the joint. Synovial fluid is the liquid lubricant in found in all joints in the body.

Whether it's cracking your knuckles or having an adjustment from your chiropractor, you've heard the "pop" and you've most likely experienced relief when the "pop" occurs.

Every time I bend my knee it snaps, what gives?

Many people think the cracking noise is bones snapping. This is not true, more likely is it a tendon moving over a bony prominence. As long as it doesn't hurt, it is something you needn't worry. Normal.

When gas isn't released from a joint capsule, several things happen. You will notice a decrease in range of motion (you're less flexible) because joints are too tight and get 'stuck'. As one joint gets 'stuck' other joints in the area need to work harder and are subject to overuse syndrome.

I'm not talking about joints being over taxed during a marathon, more like the inability to look over your shoulder.

Without good joint motion there is an acceleration of any arthritis you may have. Arthritis occurs when a joint loses motion. The best thing you can do for an arthritic joint is to move it!

Joint tightness causes muscle tightness. What follows can be muscle spasms, myofascial trigger points, and inflammation in the muscle. This is when the alarm system kicks in and deep muscle PAIN.  

Cavitating the joints is actually good for you!

Your joints should work in harmony to allow for an equal share of the load. 

When they don't, you experience more wear and teat on other areas. Like when one hip wears out before the other. Or your degenerative joint disease begins to creep into other parts of your spine.

Chiropractors know the importance of cavitating the joints in your spine to release joint pressure and increase range of motion. Most people, however, are fearful of having their neck adjusted even though this has been proven to be perfectly safe. Not surprising are the number of people with neck problems. The first being the head and neck are carried out in front of the body rather than on top of the body.
