All kinds of physical sensations work like that.

Pooping out an extra firm poop after having trouble. The pee after you've had to hold it in forever. Finally scratching an itch after a delay. There's something about our brains that hates delaying gratification, so when it happens, we get that dopamine hit a lithe harder. Same with your example; a delay of relief followed by the relief of both the original sensation and that of struggling with it. That one-two punch is like a drug. Or a mini orgasm, depending on ones wiring.

Side note to that, I've never run across "horking". I've seen hawking, hocking, and even hacking, but never horking. I like it though!
