Nashville and Louisville mark two more concert stops Miley Cyrus will miss due to her hospitalization - and she's sick of it.

"sick of waking up to needles," Cyrus tweeted early Friday (April 18) morning. " #goingthruit #floydfriday"

The former Disney Channel star has been hospitalized in Kansas City since Tuesday for an extreme allergic reaction to a prescribed antibiotic, according to her rep.

Since being admitted to the hospital, many have been wondering when Cyrus will be discharged and how many of her "Bangerz" tour dates will be canceled or postponed. Apparently, some people have been spreading rumors about the singer's health condition and she isn't taking too kindly to it.

"shut the f*** up & let me heal," the "Wrecking Ball" singer tweeted April 17. "stop scaring my family, friends, & fans."

She continued: "So many ignorant stories out there no one is reading the official statement and these dumb asses are scaring my fans."

The singer also posted a "hospyselfie" to her Instagram account on April 17 .

"This type of extreme reaction can last from 5 to 27 days in these types of cases," Cyrus's rep said. "She will remain hospitalized and is under a Doctor's care until we see some improvement in her condition … Miley is devastated about missing shows and possibly disappointing her fans."

The Nashville concert has been postponed to Aug. 7 and the Louisville show for Aug. 9. No word on which of Cyrus's other tour stops will be postponed, as of yet.
