Not to mention there are vast degrees of pain tolerance. I'd probably rate my cracked rib experience** as a 6*, whereas someone else might insist their ingrown toenail is a 9.
So in that vein, I must say that The New Improved Pain Scale by Hyperbole and a Half is made of pure awesome and win.
*EDIT: Someone in the comment thread works on the same pain-scale logic as me:
10/10 is unconscious from pain. 9/10 is pain so intense that I can't speak. 8/10 is pain so bad I can only speak to attempt to communicate the pain. If I'm coherent but the pain is seriously interfering with my motor capacities, it's 7 or below.
I once watched someone banging on a counter, demanding to be seen immediately, because he had 10/10 pain. BS, man. You can stand, you can speak, you clearly don't KNOW what 10/10 pain is.
**EDIT 2: For those who don't know, I didn't just crack a rib, I managed to do so while I had viral bronchitis. Which means A. they couldn't wrap my ribs to stabilize it, as that would impede my lungs and likely cause pneumonia, and B. I was constantly coughing, sneezing, and doing other uncontrollable physical actions that were perpetually spreading the break and letting it snap violently back together over and over and over. This was why Vicodin became My One True Very Special Bestest Friend for a month. Overall that was about a 6 IMHO: constant pain that REALLY fucks up your functionality, but you CAN still just barely go about your day to day life.
