Sinead O'Connor was rushed to the hospital last week after having an abdominal aneurysm, according to a Jan. 23 NewsMax report.
The singer best known for the 90s hit "Nothing Compares 2 U" reportedly fell ill last Tuesday. Her sister took her to a local hospital. The singer was then transferred to another medical facility.
Physicians diagnosed O'Connor with kidney stones and discharged her on Friday, according to an MSN.com report.
O'Connor was rushed to the hospital again, two days later. She suffered from severe pain. O'Connor was prescribed with Demerol, a powerful painkiller, according to an Ireland Independent newspaper.
O'Connor told A&E that she doesn't believe it was kidney stones that caused the pain. She believes that it was emotional trauma from an incident that happened a week prior. O'Connor hasn't spoken out about the trauma.
Sinead O'Connor made headlines last year when she told Miley Cyrus not to "prostitute" herself. The two singers went back and forth through a series of tweets and long letters. In the exchange, O'Connor revealed that she suffers from bipolar disorder.
