In addition to revealing the Pain Killer Tour, the four bandmates also dropped their album artwork via Instagram. In an interview last month with Rolling Stone Country, the bandmembers said they instantly knew the album would be titled Pain Killer.

"We knew the record was going to be called Pain Killer way on into the process because we love that song," said Karen Fairchild. "That song is really kind of tongue-in-cheek - 'be the person that numbs my pain.' We started talking about tying that thread through the whole record, to ease your pain. Don't we want the whole record to do that for people, anyway? Whether it's a sad moment, or a song that's more thoughtful and has a lot more substance in the lyric, we want music to take us away. Pain Killer fits, that's the common thread through all the songs."
