Award-winning pop star Sia has revealed that she is suffering from a genetic condition that leaves her with chronic pain.
In an emotional Twitter post, the Australian singer-songwriter said she had Ehlers-Danlos Syndrome (EDS), a rare genetic condition that can cause debilitating joint pain and extreme fatigue.
Sia, 43, who is known for hits including Elastic Heart and Sean Paul collaboration Cheap Thrills, is known for evading the public eye, often covering her face with elaborate wigs.
But in a rare personal announcement, she tweeted: “I just wanted to say to those of you suffering from pain, whether physical or emotional, I love you, keep going.
"Pain is demoralizing, and you're not alone".
The post received more than 77,000 likes in 14 hours, with people praising the star for being “honest” and “incredibly strong”.
One Twitter user commented: “Thank you for sharing. I’m also an ehlers danlos warrior. This disease is a beast and your music has carried me through many moments in my fight.”
According to the UK's National Health Service there are 13 types of EDS, which is caused by faults in certain genes which weakens connective tissue. The most severe forms of the disease can be life-threatening.
Sia has opened up in the past about her addiction to alcohol and pain medication.
In a tweet last year, she celebrated reaching "eight years sober".
