Ozzy Osbourne says he has experienced a significant improvement in his health since undergoing major surgery.

The 73-year-old heavy metal singer-songwriter, who revealed he has Parkinson's disease in January 2020, opened up about his recovery during a Wednesday appearance alongside his wife Sharon, 69, on "Good Morning America."

"Before I would be talking to you like this," he told correspondent Chris Connelly, as he hunched over in his chair.

Sharon explained that Ozzy was in agonizing pain ahead of the surgery. 

"These metal plates were working their way out," the former "The Talk" host said. "The debris was rubbing on his spinal cord. He would literally be crying in pain some days." 

The former Black Sabbath frontman has struggled with a number of physical ailments over the years. In 2003, he almost died in an ATV accident when his quad flipped onto him while he was riding around his London estate.

Ozzy also underwent an operation after suffering a bad fall in 2019. He told Connelly, "I had to have surgery in my neck, which screwed all my nerves."

The musician said that his mobility these days is "not great".

 "I have to negotiate everywhere I want to go and I tire easily. But I am well. My family has been absolutely wonderful while I've been laid up," Ozzy added.

"He’s been a pain in the butt," Sharon joked. "Everything from heartbreaking to soul-destroying to the joys of his getting better."

Ozzy is set to give his first U.S. performance in two years on Sept. 8 at the first day of the NFL season. The football organization announced Monday on social media that the "Shot in the Dark" hit-maker will be the half-time performer for the game between the Los Angeles Rams and the Buffalo Bills.

He last took the stage stateside at the 2019 American Music Awards when he joined Travis Scott and Post Malone for a performance of their collaboration "Take What You Want".

Ozzy's thirteenth solo studio album, Patient Number 9, will be released the day after his NFL half-time performance.

During his interview with GMA, Ozzy discussed taking the stage for the first time since 2019 when he performed at the Commonwealth Games in his hometown of Birmingham, England last month.

"When I get on a stage, something takes over," he said. "My spirit becomes alive."

Sharon added, "There were 30,000 people there and as soon as Ozzy came up, they were all crying because they just couldn't believe he was there."

"It wasn't that bad," Ozzy told her.
