Ozzy Osbourne diagnosed with Parkinson's disease

Ozzy Osbourne has revealed he is battling Parkinson's disease.

The Black Sabbath singer, 71, told US TV show Good Morning America (GMA) he was diagnosed with the neurodegenerative disease following surgery after a fall in February 2019.

He said it had been "terribly challenging" for him and his family.

"I did my last show New Year's Eve at the Forum. Then I had a bad fall. I had to have surgery on my neck, which screwed all my nerves and I found out that I have a mild form."

He said he's now on medication for Parkinson's and nerve pain following the surgery. He also has numbness down one arm and his legs are often "going cold".

"I don't know if that's Parkinson's or what. That's the problem, because they cut my nerves when they did the surgery. It's a weird feeling."

His wife Sharon told GMA the diagnosis isn't a death sentence "by any stretch of the imagination".

"It affects certain nerves in your body. You have a good day, a good day, then a really bad day."

Rumours had been circulating about his health, including one report from Radar Online earlier in January that claimed he was "bedridden" and "losing his marbles".

Osbourne's daughter Kelly rubbished the claims, saying while he'd had a rough year, the attacks were "utter bullshit".
