Ozzy Osbourne felt "helpless" in hospital

He said: "I cannot describe to you the helpless feeling that I had. I had to use [a walker] to go for a pee. I had to have nurses, day and night. Just being in hospital is enough to drive you nuts. I thank God I didn't paralyse myself when I had that accident. I wouldn't be here now. I would have jumped off the f***ing roof - or fell off the roof, whatever."

And the 'Mama, I'm Coming Home' hitmaker admits he thought he "cheated death" after his quad-bike accident.

He added: "I thought I'd cheated death once again. I was getting a strange feeling sometimes, like nerve pain going down my arms. I used to think it was wear-and-tear from being on the road and didn't give it a second thought. When they do surgery on your neck, they cut through all the nerves, and it f***ed everything up. So I'm wobbling all over the place. And since they cut through the nerves, my right arm feels permanently cold. You'd get a warm feeling in your hands. I wake up with it, and I go to bed with it. I'd never heard of anyone needing nerve-pain medication."

Ozzy cannot wait to go back on tour and hopes he'll be ready by January.

He told Rolling Stone magazine: "For the first, say, four months, I was absolutely in agony. I was in agony beyond anything I ever experienced before in my life. It was awful. I'm taking physical and occupational therapy classes, but the progress is very slow. They say it's going to take at least a year. I'm hoping that I'll be OK and ready to go by January [when the tour resumes]. I'm really keeping my fingers crossed."
