Madonna has cancelled three tour dates on medical advice after suffering "overwhelming pain," the singer has said.
The 61-year-old was due to perform in Boston, Massachusetts, from November 30 to December 2 as part of her Madame X tour.
However, Madonna announced on Instagram the performances had been cancelled on "doctor's orders".
"Please forgive this unexpected turn of events," she said.
"Doing my show every night brings me so much joy and to cancel is a kind of punishment for me, but the pain I'm in right now is overwhelming and I must rest and follow doctor's orders so I can come back stronger and better and continue the Madame X journey with all of you."
The shows, which would have taken place at the Boch Center Wang Theatre, will not be rescheduled.
Promoter Live Nation blamed "tight scheduling". Refunds will be given.
