After a while, my head felt about to split open.
My head felt funny, but I didn't know what had hit me.
Her head felt as if it were made of lead.
I don't remember what she said, but it made my head feel funny.
He tried to sit up, but his head felt light.
My head felt as if it would burst at any moment.
But even with them on, after a couple of hours my head felt as if it were coming apart.
She nodded, her head so close to his he could feel the movement.
My head felt all full of cotton when I tried to remember what had happened.
Although death might have been an improvement over the way his head felt right now.
