Miley Cyrus' Health Issue Continues: Singer Cancels Amsterdam And Belgium Shows

Miley Cyrus has reportedly fallen ill once again.

After a brief period of her symptoms subsiding, the pop star is dealing with the returning side effects of a recent allergic reaction to her sinus infection medication.

"After a period of improvement, Cyrus' symptoms have returned and doctors will not permit her to travel," Cyrus' management team confirmed to PEOPLE Magazine on April 30.

Cyrus was hospitalized and placed on medical rest on April 15 after experiencing a severe allergic reaction to medication. Following the hospitalization, Cyrus canceled shows in Kansas, North Carolina and Michigan, before opting out of the remainder or her U.S. tour and rescheduling the concerts for this August.

Now that Cyrus has been restricted from traveling, she has been forced to reschedule two more concerts from the European leg of her Bangerz Tour, one in Amsterdam, which was to take place on Fri., May 2, and one in Antwerp, Belgium, which was set for Sun., May 4.

Although Cyrus hasn't released an official statement regarding the news, she did post several clues online in the days leading up to her latest health update.

On April 28, Cyrus tweeted a message to fans which read, "spoke to soon." Hours later, she followed it up with a post which said, "R u f**king kidding me?!?!?!?? #aprilcangof**kitself." Then, on Wednesday, as news of her canceled show hit the web, Cyrus posted a message filled with crying cats.

Miley Cyrus is expected to be well enough to perform her scheduled show in London, England on May 6.
