Do your joints often feel like you want to crack them? I keep feeling a tightness and stiffness in my joints that makes me want to stretch and crack them to loosen them up. Also, is it unusual that I can every joint in my body? (this even includes ankles, wrists, jaw, hips etc.) I think it might be from the ligaments and tendons being less flexable and stiff causing resistance to what should be smooth movement of the joint. Just wondering if it was common.
