I have a headache. I was grinding my teeth all night. My eyes huirt. I need to massage my skull.
Maybe you need a mouth guard to wear when you sleep. 
I have one, but my temporanry crown prevents it from fitting, so I am using a cheapo drugstore one so I don't file my teeth down even more. I think this nightguard is why I have headaches. It isn't so different from going without a nightguard except for protecting my teeth from being crushed to shards.
