When you crack your neck and back, you are haphazardly manipulating and straining the muscles around your spine to forcefully cause the crack. The greatest risk with this is creating hypermobility of the joints, which could lead to increased pain, and predispose you to increased vulnerability at the joints.
Engaging a non-trained friend to help in the cracking process is even more risky an endeavour. When a non-trained person assists in cracking a friend’s back, they can exert a force that’s too hard, leading to muscle injury (such as a sprain). Stop that habit of asking your friend to stand or walk on your back to crack it!
Conversely, a registered professional, such as a Doctor of Chiropractic, or an Orthopaedic Doctor, can safely address the issues you are having. Prior to conducting a chiropractic adjustment, we do a comprehensive assessment of your medical history, and current issues (via a physical examination, and often imaging) to diagnose your condition, even before conducting an adjustment.
