Ozzy Osbourne’s long battle with health issues
The 'Paranoid' singer was diagnosed with Parkinson’s in 2003, the same year he suffered a near-fatal quad bike accident.
In 2019, a fall at his Los Angeles home aggravated the injuries from that accident. He had suffered a fractured vertebra, eight fractured ribs, and a broken collarbone in the accident.
Sharon Osbourne later revealed that after the bike accident, "he had stopped breathing for a minute and a half and there was no pulse,” all thanks to a security guard who resuscitated him. It led to him being placed in a coma for several days.
He also dealt with blood clot issues in his legs, requiring his blood pressure to be checked 15 times a day.
By 2020, Osbourne mentioned that he had been "laid up for a year" and unable to walk without help, or at all, due to the accident.
Ozzy Osbourne’s final performance and tearful goodbye
Ozzy Osbourne’s death came just weeks after his final show in his hometown of Birmingham, England, where he reunited with Tony Iommi, Geezer Butler, and Bill Ward for the first time in two decades.
The 'Mama, I’m Coming Home' rocker performed five songs in his solo set, ending with 'Crazy Train' before a crowd of 40,000 fans at Villa Park stadium.
Emerging from beneath the stage on a black throne, he told the audience, “Let the madness begin!” and later added, “I don’t know what to say, man. I’ve been laid up for like six years."
