Well, Metallica's quite good for stimulating the adrenals ....

but if you're in a lot of pain, try Slipknot, Slayer or Rage Against the Machine. Or maybe a bit of Hurt CoPain's Nirvana. All guaranteed to smash your eardrums, deaden your senses and dull your brain so much you'll simply forget those petty insignificant little pains!    ;-)
