@narelled23 That’s great! I am going through something similar with a dental appliance to align my jaw and PT to work on my cervical spine. When C1 is rotated, as mine was, it caused the jaw to be misaligned. It’s in line now and I stopped having pain in my ear too. I have a narrow jaw, and this appliance will help expand my jaw and make it easier to breathe. I was tested and do not have sleep apnea. I have allergies and asthma that affected my sleep oxygen levels.
