Ozzy Osbourne is still struggling to walk 6 months after he had surgery on his spine.
The rock legend offered an update on his health whilst appearing on SiriusXM and said he was unsure his 2023 tour would go ahead.
Osbourne said: "It is so f***ing tough because, I mean, I want to be out there. I want to be doing it. This f***ing surgery this guy did. F***ing hell, you have no idea."
The Black Sabbath singer continued: "The thing is my head is all right, my creativity is OK, my singing OK but I just can’t f***ing walk much now."
Osbourne also discussed how the prolonged recovery from the surgery was getting him down: "I can’t begin to tell you how f***ing frustrating life has become. It is amazing how you go along in life and one stupid thing can screw everything up for a long time. I have never been ill this long in my life."
Osbourne, who has also been diagnosed with Parkinson's disease, said he was told he needed the surgery to prevent disability: "That surgeon told me if I didn’t have the surgery there would be a good chance I would be paralysed from the neck down."
The Paranoid singer has suffered with a number of health issues in recent years including being hospitalised with the flu and placed in intensive care.
He also sustained serious injuries from a fall in 2019 that led to metal plates being placed in his back.
Before the surgery earlier this year, Ozzy's wife Sharon said that the operation would "determine the rest of his life".
The couple recently moved back to the UK after spending much of the last 20 years living in Los Angeles.
