If you’re hearing popping sounds from your upper back (cervical spine), it could be due to your tendon snapping, gas being released from between the joints. Excessive snapping could mean there’s a problem in your joints, and you might need to get checked for osteoarthritis. Check for signs like pain in the upper area like neck pain and shoulders. There’s less stability between the joints and nerves, and if not checked on time, it can result in more severe issues.
