Why am I getting hot flashes- I'm 16?

It seems like almost every day I get these bursts of a hot-flash feeling, I start sweating and it seriously feels 100' in whatever room I'm in. The thing is, I don't actually get a fever. I would think it would be menopause but, like I said, I'm 16. And its not just during/before/after my period, its almost every day. What could this be?
