Add insult to injury

Hello,

I'd like to know whether the idioms "add insult to injury" and "rub salt in the wound" are still used. Is there any other way to say the same in a figurative manner?

Thank you in advance.

They're both in use in BrE.

They don't sound dated to me.

They're still commonly used in AmE as well.

In a similar vein, there's "kick someone while they're down".
