MUMBAI: Singer Katy Perry is suffering from chronic knee pain and has taken to having acupuncture three times a week in a bid to save her ailing joints.
The 30-year-old, who performed her ballad 'By the grace of god' at the Grammy Awards on 8 Feburary, said her constant performing has taken its toll on her body, reports femalefirst.co.uk.
"My knees are giving out on me now. I do acupuncture every two or three days," The Sun newspaper quoted Perry as saying.
She added, "I tour with a stage that goes from the front of the house to the back of the house with a triangle thrust that is a moving treadmill, like I think I'm some kind of Olympic athlete."
