What is the English equivalent of a vulgar expression for continuous nagging?
Solution 1:
I think the closest fit, albeit not as vulgar, is:
They chewed my ear off.
Solution 2:
A harpy according to Dictionary.com is
- a ravenous, filthy monster having a woman's head and a bird's body.
- (lowercase) a scolding, nagging, bad-tempered woman; shrew.
So for example, you could say, 'I wish my wife would quit harping on me to take the trash out.'
Solution 3:
To do someone's head in (British informal)
Defined under head, phrases (defn. 10) as:
make someone feel annoyed, confused or frustrated
'My relationship with my publicist was doing my head in.'

Solution 4:
Here are some ideas:
They got on my nerves. (You're right, this is not very strong.)
They drove me up the wall, drove me nuts, drove me up the wall, drove me crazy, drove me mad, drove me berserk.
He kept at me until I was ready to wring his neck.
They made my life a living hell. (My favorite)
Solution 5:
Carping is a possibility, although it doesn't have the nuance of "brain damage via nagging".
From m-w.com: "Marked by or inclined to querulous and often perverse criticism."
