Is Cracking Your Knuckles Bad For Your Hands And Fingers?

Many people pop or crack their knuckles,out of habit or to make their fingers
 feel loose or more mobile.

The reason behind these popping sounds has remained unclear,but a study published seems
to have solved the knuckle-cracking conundrum.
Using sophisticated magnetic resonance imaging of the finger joints.

Researchers found that the sound occurs when a bubble rapidly forms in the lubricating synovial fluid within the joint.

If you're concerned that knuckle-cracking might lead to arthritis,a 2011 study involving 215 people,ages 50 to 89,found no difference in arthritis risk between those who cracked their knuckles habitually and those
who did not.

Some experts think that cracking your knuckles might even be good for the joints.
Overall,cracking your knuckles doesn't not appear to be harmful,but if it's
accompanied by pain or swelling,see your doctor.
