At the beginning of the first book Percy gets attacked by his math teacher, Mrs. Dodds. She gets him into an empty room and turns into a Fury (a kindly one).
Percy gets caught on fire in the Battle of the Labyrinth when the telekhines throw excessive amounts of lava at him.
Oh man there are so many... Let's see: In the LT: He gets hurt training in Camp Half-Blood, gets hurt during capture the flag, gets hurt all they times he gets attacked by monsters, gets hurt during his fight with Ares... Come to think of it, I think Percy gets hurt in pretty much every chapter of every book after about chapter 3 of TLT all the way up till after his final fight with Kronos.
