Head feels like a cement block

Can anyone else relate?  Every morning, especially in these cooler months of the year, I wake up and my head feels like a cement block, with a dull pain bordering on a headache.  The only thing that seems to help is to steam my face over boiling water.  I suspect it may be my sinuses.   It really makes my mornings rough and off to a bad start.  I'd like to go back to bed and lie down with my sinus "bed buddy," but that takes time.  Thanks for any ideas on helping this.
