i do the same thing the back of my head and neck make a crackling sound sometimes it helps and sometimes it stiffens it up. my doctor listened but gave no advise. mandy876
When you crack your neck or any other bones/joints in your body you are releasing gas pressure from between the bone. Sometime when the bones or joints are pushed it the pressure pushes down on a ligament or tendon giving you pain. It's ok to crack your neck, or any other joint in your body. Maybe you should try seeing a chiropractor for help and tips on cracking. Take care
