Dazed,

It sounds to me like stress/ anxiety symptoms. I like mark am doubtful you have a major disease.

One of my first clues to anxious thoughts setting in is clinched teeth and a sore jaw. I have just recently realized that the clinching is what gets my head injury site sort most of the time now and not the injury itself.

Anxiety is a funny creature but is beatable with knowledge and persistence. I learned a lot about it at anxietycentre.com this winter.

The good thing is you are discovering this about yourself at a young age and can make necessary changes before you have a long life of ingrained anxious habits and behaviors to change, it gets hard then. I wish I had known what I know now at your age.
