[Lovecraft] Can humans hurt Eldritch beings?

I understand that Eldritch beings are extra dimensional creatures beyond our comprehension, but does that mean that they can’t be hurt by us? The European government is incomprehensible to a rat, but it can carry even smaller bubonic plagues carrying fleas that kills half the population. What about a thin piece of paper or a thin sheet of steel? They are effectively of lesser dimensions then is, but try cutting a person with it a hundred million times and they would probably take considerable damage. You probably can’t directly hurt these abominations, but the fact that they even notice us(Earth being a place of slumber) probably means that we’re worth some consideration, no matter how small.

If we're going by the pure canon of Lovecraft's books, then yeah. Some guy crashed a boat into Cthulhu and made him go back to sleep for another thousand years. If we're going by the more extreme examples, then sometimes you can hurt them, but similar to how an ant can hurt a human, it does nothing to stop them and set best highly irritates them.
