Neck Pain
A cracking sound which occurs once as you turn your head but then is not reproducible for a period of time is usually from something called cavitation. I wrote an article on this which you can read on our website (Is The Crack In Your Neck Worth It?). When you twist and bend your neck, you stretch the joints. Inside each joint is a liquid called synovial fluid that contains gases like nitrogen, oxygen and carbon dioxide. This liquid exerts a certain amount of pressure against the ligaments around the joint (called the joint capsule). The stretching causes the pressure inside the joint to drop. When the pressure drops, the ligament gets sucked into the joint and a bubble of carbon dioxide forms. The formation of the bubble creates a popping sound as it comes out of the synovial fluid (cavitation) and increases the volume of synovial fluid temporarily (by about 15%). The increase in volume pushes the ligament back into place creating another popping sound (these occur so fast you hear only one sound). You cannot repeat the snap, crackle, pop for about twenty minutes or until the bubble dissolves back into the synovial fluid.
The other reasons for a cracking sound, and these typically occur on a repeated basis, include changes in the shape of the joints and changes in the thickness of ligaments. If your joints have extra bone (which forms in response to a loss of intervertebral disc height), then as you move your head the extra bone can cause a "collision" - one part of the joint bumps into another part and creates a cracking sound. In some cases the ligaments which attach to the joints will become thicker (again due to changes in the disc height). Occasionally, as you move your head, the ligament will slip over the edge of the bone and you may hear a snap or a cracking sound.
The supplements are:
1. Glucosamine (GLUE-CO-SAH-MEAN)
2. Chondroitin Sulfate (CON-DROY-TIN-SULF-ATE)
3. SAMe (SAMMY)
4. Omega Three Fatty Acids
5. ACES (Vitamin A, C, E, and Selenium)
