Miley Cyrus can’t catch a break. Just when the singer thought she had finally recovered from her health issues, she’s back to feeling unwell enough to perform on tour.

A source has shared with E! News that the ‘Bangerz’ star has once again “had a health setback and her allergic reaction issues have returned.”

Poor Miley! Just days ago she went on air with Ryan Seacrest to talk about her recent (and thought-to-be-over) health scare that forced her to reschedule the remaining U.S. stops of her Bangerz Tour.

“Everyone had this ongoing little cough thing,” Miley said. “I got medicine, I had to cancel a show, and I felt like I had a flu/cold situation. They gave me some medicine, I was on it for five days, and everything was all good.”

That is, until Miley began to feel worse and her doctors realized she was having a severe allergic reaction to her medication.

It seemed like a week in the hospital and some time off was exactly what the singer needed to recover and get back on the road. She even took a moment to hop on Instagram to share a pun with Smilers, posting a duck-faced oxygen mask with the caption, "This hospitals full of a bunch of QUACKS (get it??? Quacks) #punnyeveninthehospy #stayinglightlovingandpositive #imissbangerztour #tryingtonotbebitter."

New medicine and much-needed rest didn't seem to do the trick, unfortunately, as the pop singer has announced the temporary cancellation of her upcoming Amsterdam concert. The rescheduled show, originally set for this Friday (May 2), was going to be the kick-off for the six-week European leg of her tour. According to E!, Miley is also planning to postpone her May 4 show at the Sportpaleis in Antwerp. Hopefully she recovers in time to make the rest of her tour dates.

Feel better soon, Miley!
