A few days ago I yawned, and had this extreme pain in my upper neck, right below my chin. I have experienced this pain before, but not like this. After the yawn occurred, I experienced massive head pain. The pain did not stop, and has continued threw the week. And I also have experienced the neck pain every so often. But now, after over talking/volunteering, I'm experiencing the pain non stop, And my head hurts quite a lot. Also when I lay my head down I can feel a very hard beat in my head. I feel the pain also moves to my teeth, and even down my chest. I'm very worried to what this might be. In addition, I panic when I get unfirmiliar pain, so I'm over worrying, thinking I might die. Would like suggestions, or even if you have experienced something like this before even?
