Lady Gaga has been forced to cancel the Rio concert of her world tour, citing “severe pain” for which she had to be hospitalised.

She wrote on Twitter and Instagram: “It’s not simply hip pain or wear & tear from tour, I’m in severe pain. I’m in good hands [with] the very best doctors.”

On her Instagram post she shared a photo of her tattoo that reads “Rio”, adding “Remember years ago when I tattooed Rio on my neck, the tattoo was written by children in the favelas ... You hold a special place in my heart I love you.” In another post she wrote: “I would do anything 4 u but I have to take care of my body right now.”

The pop star has fibromyalgia, a chronic pain condition which she has previously documented on social media; in November she posted a description of the ice baths, infrared saunas and emergency blankets she uses to manage her condition.

She has said that her forthcoming Netflix documentary, Gaga: Five Foot Two, will document her experience of fibromyalgia, “to help raise awareness & connect people who have it”.

In our documentary the #chronicillness #chronicpain I deal w/ is #Fibromyalgia I wish to help raise awareness & connect people who have it. — xoxo, Gaga (@ladygaga) September 12, 2017

Her tour continues in Barcelona on 21 September, with five UK concerts in London, Birmingham and Manchester beginning 9 October.
