What is Ramsay Hunt syndrome, the condition affecting Justin Bieber?

Justin Bieber has revealed that he is suffering from a rare

condition that has paralyzed one side of his face.

Earlier this week, the Canadian singer canceled a number of upcoming shows because of illness,

and on Friday he told fans he has been diagnosed with Ramsay Hunt syndrome.

It is from this virus that attacks the nerve in my ear and my facial nerves,

and has caused my face to have paralysis,” the 28-year-old singer said in an Instagram video.

“As you can see, this eye is not blinking.

I can’t smile on this side of my face.

This nostril will not move.”
