Justin Bieber's Philly concert postponed due to rare syndrome

PHILADELPHIA (WPVI) -- Justin Bieber's upcoming concert in Philadelphia has officially been postponed due to an ongoing medical situation.

This week's Justice Tour show at the Wells Fargo Center was postponed after Bieber discovered he was diagnosed with a rare disorder.

Concert organizers stated details on the rescheduled Philadelphia show will be provided.

Both shows at Madison Square Garden, which were scheduled for Monday and Tuesday, were also postponed.

A statement from Bieber's tour promoter, AEG Presents, posted to MSG's website reads:

"Justin is receiving the best medical care possible and is determined to resume the tour as soon as he and the doctors feel he is able to continue."

Last Friday, the multi-Grammy winner posted a video to his Instagram account to say that he is suffering from Ramsay Hunt syndrome.

The syndrome causes facial paralysis and affects nerves in the face through a shingles outbreak.

Bieber had already canceled his shows in Toronto and Washington, D.C. prior to posting his video.

The 'Ghost' singer demonstrated in the video that he could barely move one side of his face, calling the ailment "pretty serious."

"For those frustrated by my cancellations of the next shows, I'm just physically, obviously not capable of doing them," he said. The singer added, "My body's telling me I've got to slow down. I hope you guys understand."

Bieber said he's unsure how long he'll take to heal. But he appeared positive about making a full recovery through rest and therapy.

"I'll be using this time to just rest and relax and get back to a hundred percent, so that I can do what I was born to do," he said.

Derick Wade, a consultant in neurological rehabilitation and visiting professor at Oxford Brookes University in the U.K, told Sky News that recovery time can vary significantly.

"If a nerve is damaged in this way, it can recover in some people very quickly, in a few days or a few weeks and in other people can take several months. So it's a very unpredictable affair," he said.

In March, Bieber's wife, Hailey Bieber, was hospitalized for a blood clot to her brain.
