Ozzy Osbourne believed he was dying after a fall at his home left him in "constant pain".

The rocker thought he was suffering from a terminal illness and that wife Sharon Osbourne was not telling him the truth about his condition after the accident, which came after the 70-year-old suffered a bout of pneumonia earlier in the year.

Describing the fall, Osbourne told the Daily Mail's Weekend magazine: "I went to the bathroom in the night, lost my balance and landed flat on my face. I saw this big white flash when I hit the floor and I thought, 'You’ve finally done it now'.

"I knew it was bad, I thought I was paralysed, so very calmly I said, 'Sharon, I can’t move. I think I’ve done my neck. Phone an ambulance'."

Reflecting on the aftermath which saw him undergo three operations, he said: "The pain is constant. The first six months I was in agony. I’d say, 'Sharon – you’re not telling me the truth. I’m dying, aren’t I?'.

"I thought I’d got some terminal illness because the improvement was so slow. I’m getting better, but after the surgery the nurses asked me on a scale of one to ten how much pain I was in, and I said, '55!' Six months of waking up in the morning and being unable to move is a miserable existence.”

Earlier this month, the singer assured fans he was "not dying" after announcing that he would be postponing some European tour dates.

He told his social media followers: "At the beginning of this year I had a bad fall, had to have surgery, so I’ve got more nuts and bolts in my neck now than in my car.

“I’m not dying, I am recovering. It's just taking a little bit longer than everyone thought it would.”
