Gaga went on to explain that she is suffering from severe pain. A statement, posted on her behalf read:
"Lady Gaga is suffering from severe physical pain that has impacted her ability to perform. As a result, she sadly must withdraw from this Friday's Rock in Rio performance. Lady Gaga is under the care of expert medical professionals. She sends her love to all her fans in Rio and thanks them for their support and understanding."
She shared another photo of herself lying in her hospital bed. It showed only the side of her face and her "Rio" tattoo.
"I was taken to the hospital, it is not simply hip pain or wear and tear from the road, I am in severe pain. But am in good hands w/ the very best doctors. Please don't forget my love for you," she wrote in the caption. "Remember years ago when I tattooed Rio on my neck, the tattoo was written by children in the favelas. [RIO] You hold a special place in my heart I love you."
Gaga's Instagram messages come just a couple of days after she revealed that she's been battling fibromyalgia. In the midst of promoting her new documentary Gaga: Five Foot Two, in which she discusses her struggle with the illness, she also headed to Twitter to mention it by name for the first time.
"In our documentary the #chronicillness #chronicpain I deal w/ is #Fibromyalgia I wish to help raise awareness & connect people who have it," she tweeted. "I am praying that more and more people come forward and we can all share what helps/hurts so we can help each other."
