Everyone’s probably cracked their knuckles, neck or back. But what is the crack noise?
The sound is a result of a force of movement being applied to your joint. Majority of the joints in our body has synovial capsules which contains synovial fluid which lubricates our joints. When force is applied to the joint, the pressure of the synovial fluid changes. This occurs quickly, leading to formation and release of gas bubble. The gaseous release of pressure from the joints creates the audible ‘crack’.
Is joint cracking bad? Yes and No. Cracking your neck can be bad if you don’t do it correctly and if you do it too often or forcefully. Cracking your own neck too hard can strain your muscles and joints. Feeling like you need to crack your neck a lot may be a result of hyper mobility. Hence, constantly trying to crack something that’s already hyper mobile may sprain your ligaments.
If you constantly give in to the urge of cracking your neck but never feel satisfied, then you may need to see an expert for that. As the hyper mobile joints would want to move first no the hypo mobile joint. This can lead to pain, stiffness and even pinched nerves. Getting an expert to correct the hypomobile will benefit you.
