Ozzy Osbourne is no longer able to walk as his health continues to deteriorate due to Parkinson’s disease. On February 5, Sharon Osbourne, 72, discussed her husband’s ongoing battle with the illness in an interview with The Sun. Despite the challenges, she expressed excitement about Ozzy, 76, reuniting with Black Sabbath for the first time in two decades at his final concert this July.

“He’s very happy to be coming back and very emotional about this,” she said.

“Parkinson’s is a progressive disease. It’s not something you can stabilize. It affects different parts of the body and it’s affected his legs,” she added. “But his voice is as good as it’s ever been.”

Per The Sun, Ozzy talked about his health on his SiriusXM radio show. He said, “I have made it to 2025,” he said. “I can’t walk, but you know what I was thinking over the holidays? For all my complaining, I’m still alive.”

“I may be moaning that I can’t walk but I look down the road and there’s people that didn’t do half as much as me and didn’t make it,” he added.

Sharon later explained that Ozzy works with a physiotherapist every day to keep things moving along. “He’s fine,” she adds, “…as fine as you can be with Parkinson’s.”

In 2003, Ozzy Osbourne was diagnosed with Parkinson’s, but he did not publicly announce his diagnosis until 2020. More recently, Osbourne’s health has suffered greatly.

On Osbourne’s SiriusXM channel Ozzy Speaks, he shared a recent health battle. He explained that he had blood clots in his legs and “they put a filter in your artery” to prevent the blood clots from traveling to the heart or brain. He recently had the filter removed, but that doesn’t mean his health battle is over. He explained that “it’s disappointment after disappointment.”

Osbourne shared that he is “in constant pain,” yet he tries “to stay away from the pain medication.”

According to PEOPLE, Ozzy fired back at critics of his health struggles, bluntly telling them to “f— off.” He reassured fans, stating, “I’m far from being on my last leg.”
