I have been experiencing stiffness and aching in my teeth and jaw for a long time. The issue worsens when I eat food. My ears also will often get blocked and my Eustachian tubes will not open when I swallow. I also experience stiffness in the back of my neck. Cracking my neck seems to alleviate some of the symptoms, I have tried TMJ stretches and anti inflammatory medications but they only help for a short time. Please help!
