Justin Bieber reveals facial paralysis virus full video

Singer Justin Bieber has revealed he is suffering from facial paralysis after cancelling shows this week.

The 28-year-old said in an Instagram video that the condition is due to a diagnosis of Ramsay Hunt syndrome.

He had been due to play in Washington DC and Toronto earlier this week, with concerts also planned in New York and Los Angeles in the coming weeks.

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

The Mayo Clinic says that for most people, the symptoms of Ramsay Hunt syndrome are temporary, but can become permanent.

The inability for patients to close one eyelid can also cause eye pain and blurred vision, the organisation says, adding that it is most common in people over 60 years old.

In March, the singer's wife, Hailey Bieber, was admitted to hospital due to a blood clot in her brain.

She later said she had suffered a stroke and had undergone surgery to close a hole in her heart.
