I'm a 15 year old girl and in one of my postd before I explained about me having well what feels like something moving back and forth in my head when I turn my head which I do no no what it could be? :_(

But thing is I never get headaches is that a good thing ?

Consider yourself lucky! I have constant migraines and have to take prescription meds for it!

You need it scanned CT will show it if there is something-get it done asap! The sooner you get it checked, the better.

Feeling something moving in your head is not normal and you should ask your parents to take you to see your family doctor. Not having headaches is likely unrelated and not a bad thing.
