Firstly, Hook wasn't affected by the curse keeping everyone in Storybrooke since he wasn't in Storybrooke when that part of the curse began. So he kept his memories. Secondly, I imagine the poison on Hook's hook is fairly nasty. Probably from Neverland. Rumple is outside of Storybrooke when he is poisoned - essentially he is human without any magic or powers or immortality. He returns to Storybrooke but when he gets there he is no longer in possession of his dagger, so he can't magically make himself healthy again because who ever holds the dagger controls the Dark One and through the Dark One, his powers.
