Hydroxyzine
"Hydroxyzine seems to help more with my reaction to pain than with the actual pain. If I take hydroxyzine while I have shin splints, I still feel quite a bit of pain; it's just that I feel significantly less distressed and distracted by the pain than I normally would be. 



It works best for pain if taken with an actual painkiller. I prefer using naproxen, as the hydroxyzine seems to counteract the stomachache I always get from this NSAID."
