And she's not happy about it.
"Sick of waking up to needles," Cyrus, 21, Tweeted early Friday morning, adding this hashtag: "#goingthruit." She also added the hashtag "#floydfriday," referring to her beloved dog Floyd, who passed away earlier in the month.
In more Tweets, Cyrus lashed out over reports that have skewed the reports of her medical condition. "So many ignorant stories out there no one is reading the official statement and these dumb asses are scaring my fans," she wrote in one. "Shut the f–– up and let me heal," she wrote in another. "Stop scaring my family, friends and fans."
She then linked to the official statement, which was released earlier this week and explains how she suffered an extreme allergic reaction to the antibiotic she was prescribed to treat a sinus infection.
According to her rep, Cyrus will remain hospitalized until her condition improves, which means potentially more canceled shows.
The Nashville show has been rescheduled for August 7, while the Louisville show has been moved to August 9. All tickets will be honored, according to the venues.
