In a new interview with Rolling Stone, Ozzy Osbourne has revealed that he had three staph infections in his right thumb and that they were potentially fatal. Ozzy noticed the infection in his thumb after a show in Salt Lake City when his thumb had swollen to “the size of a fuckin’ lightbulb.” Ozzy has rebooked the four postponed dates of the No More Tours 2 Tour have been rescheduled to next July, after a run of dates in Oceania and Japan.

Ozzy claims: “I freaked out,” regarding his thumb infection. He showed it to his wife and manager, Sharon, and she took him to the emergency room.

“I didn’t feel sick, so I was cracking jokes,” he says. “The doctor said, ‘I don’t know if you realize, Mr. Osbourne, this is a very serious problem you have.’ Sharon said, ‘Would you stop fucking making jokes?’” He laughs. “So I said, ‘Well, it’s my hand.’” The thing was, nobody was laughing. “They’re all extremely, deadly serious about it,” he says. “I judge it based on the expression and the body language of the doctor. If he comes in with a really solemn face, I go, ‘Oh, OK. My time to go is up.’”.

“You put your thumb in front of your face on your right hand, they went in by the side of the nail on the left side for the flesh under the nail,” he says. “They cut all this stuff out. Even with the numbing stuff, it was agony. It wasn’t pus, but it was the stage after pus, when it gets in the blood and goes in your body and fucking kills you. It may sound fucked up what I’m saying to you, but he was really concerned about checking my blood.”
