Ozzy Osbourne dropped a hair-raising message before his surgery.

In the past years, Osbourne went through - and survived - health issues that tested his capacity as a human. After his COVID-19 diagnosis, the rocker was scheduled to a life-altering surgery on Monday.

But hours before the "life changing" procedure starts, Osbourne delivered a sweet but hair-raising message to fans.

Through his Instagram Story, the 73-year-old singer excerpted lyrics from his 2010 song "I Love You All" and seemingly told his fans how much they mean to him.

Osbourne eerily wrote, "For all these years you've stood by me / God bless, I love you all."

He also reposted a post shared by @road_recovery on Instagram as it wished him the best for his surgery.

The Black Sabbath singer is making fans worry as his surgery requires him to have a lengthy amount of recuperation due to his age. The nature of the surgery - in which the doctors will remove and realign the pins installed in his neck and back.

The rehabilitation after the surgery will happen at his home for months, but a full-time care will also be observed.

For what it's worth, the screws in question were inserted into his spine after an accident in his Los Angeles home. He ended up having two months of recovery and rehabilitation.

Ozzy Osbourne Receives Best Support From Wife Sharon Osbourne

While his fans continuously pour their prayers and support, Osbourne's wife, Sharon, also made sure that the singer knows he is not alone in his health battle.

Last week, she revealed on "The Talk" that she would return to Los Angeles to be with her husband's side.

"He has a major operation on Monday, and I have to be there. It's really going to determine the rest of his life," she said.

Osbourne first suffered life-threatening injuries in his 2003 Quad Bike accident that left him with a broken neck vertebra. He also told The Sun years ago that he was lucky to be alive after the crash.

The issue exacerbated after a 2019 fall - where his surgery is set to focus. Per the singer, the same fall led him to suffer nerve damage.

The Black Sabbath genius then faced multiple health issues, including pneumonia, flu complications, and a hand infection that caused him to undergo another surgery. Things did not stop there as he was diagnosed with mild Parkinson's disease years after revealing that he had Parkinsonian syndrome.
