Justin Bieber says he has facial paralysis due to Ramsay Hunt syndrome, so what is it, and why Ramsay Hunt Syndrome is affecting him?

Famous singer Justin Bieber announced that he is taking a break from performing because he is suffering from paralysis on one side of his face.

In a video posted on Instagm, the singer explained that he has Ramsay Hunt syndrome, which has left him unable to move half of his face and unable to take the stage.

"It is from this virus that attacks the nerve in my ear and my facial nerves and has caused my face to have paralysis," Justin Bieber said.

In the video he said. "As you can see this eye is not blinking. I can't smile; this nostril will not move. So there's full paralysis on this side of my face."

Bieber addressed those who have been frustrated by the recent cancellations of his concerts and said he's "physically, obviously, not capable of doing them."

"This is pretty serious, as you can see. I wish this wasn't the case, but, obviously, my body's telling me I've got to slow down," he said.

"I hope you guys understand. 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."

According to the experts, Ramsay Hunt syndrome "occurs when a shingles outbreak affects the facial nerve near one of your ears.

In addition to the painful shingles rash, Ramsay Hunt syndrome can cause facial paralysis and hearing loss in the affected ear."

The Canadian singer cancelled a number of upcoming shows because of illness. Bieber has said he is focusing on resting and doing facial exercises.

Justin thanked his fans for being patient, said he's been doing facial exercises to help. He said he doesn't know how long it will take for him to recover.
