What is Ramsay Hunt syndrome, and why does Justin Bieber have it?

Bieber disclosed in an Instagram video that he has been diagnosed with 'Ramsay Hunt Syndrome,' which has completely paralysed the right side of his face. What exactly is it? Is it possible to treat it? We will explain

Justin Bieber, the Canadian pop superstar, announced on Saturday (June 11) that he was suffering from temporary facial paralysis, only days after cancelling three gigs on his world tour.

Bieber disclosed in an Instagram video that he has been diagnosed with 'Ramsay Hunt Syndrome,' which has completely paralysed the right side of his face.

This eye isn't blinking, as you can see. On this side of my face, I'm unable to smile... As a result, this side is completely paralysed.

On Friday, June 10, Justin Bieber released a video detailing the disorder with the message "IMPORTANT PLEASE WATCH." I love you all and ask that you remember me in your prayers."

Ramsay Hunt Syndrome, according to the Mayo Clinic, affects facial nerves and is caused by the same virus that causes chicken pox.

As you can see from my face, I have a syndrome called Ramsay Hunt Syndrome, which is caused by a virus that affects the facial nerves in my ear and paralyses them," he explained.
