My head was sore to the touch, but as far as I know not actually at the point of impact. My head felt like it was bruised, so it hurt to push on it or touch it, and would have a dull ache or slight burning if I wasn't touching it.

The sensation was on the top of my head, where I am fairly certain I didn't actually hit. I fell off a horse and it is possible that I hit my head on the horse on the way down but I hit it on the ground for sure.

I would notice the pain becoming more intense after being overstimulated. Over time it gradually lessened and it took more stimulus to bring it on. I haven't felt it in about 3 months now, which would have been 21 months after my accident.
