The 33-year-old Grammy Award winner's live performance at Salt Lake City and Denver, which was originally scheduled for this week, has been pushed towards the end of October, reported People magazine.
"Not very dramatic - doctor just wants me on complete vocal rest for four days to heal. Touring would be terribly easy if I lip synced," Pink tweeted.
As a result of the doctor-ordered vocal rest, Pink's originally-scheduled show at Salt Lake City's Energy Solutions Arena on October 17 has been moved to October 29.
