His vulnerable side as he reveals his health struggles and puts rumors to rest. That's how it goes He is known as the prince of but this morning for the first time legendary rocker ozzy Osbourne alongside his wife and manager Sharon is shedding light on a private health battle and the moment he says everything changed last February. 2019, a very challenging year for you. Well, it has been terribly challenging for us all. I did my last show new year's eve at the forum and I had a bad I had to have surgery on my neck which screwed all my nerves up and I found out that I have a mild form of -- It's parkin 2 which is a form of Parkinson's and it is -- there's so many different types of Parkinson's. It's not a death sentence by any stretch of the imagination. But it does affect certain nerves in your body and it's like you have a good day, a good day and then a really bad day. A year ago next month I was in a shocking state. Reporter: Before this diagnosis ozzy for years battled rumors about his physical state. Even at one point denying he had Parkinson's, all that now in the past. Parkinson's is a neurodegenerative disorder that progresses slowly in most people. But as of now has no cure. The rock icon who spent 50 years on the road and living a very public life as we all saw on his family's popular reality TV show "The osbournes." She's my whole world. Reporter: This year forced to postpone his world tour and remain largely secluded recovering at home. A hot of many case, many for the surgery. I got numbness down this arm from the surgery. My legs keep going cold. I don't know if that's Parkinson's or what. That's the problem. Because I got nerves -- when they did the surgery I never heard of nerve pain. It's a weird feeling. You said you're on a lot of medications. Parkin medications. A really, really low dose and I'm taking nerve pills. The thing is as ozzy said before it's very hard for doctors to go, well, this is your injury from your fall and this is what comes with parkin 2 and we've kind of reached a point here in this country where we can't go any further because we've got all the answers we can get here, so in April we're going to a professor in Switzerland and he deals with getting your immune system at its peak so we are going to go wherever we can go to seek answers. Lucky enough to be able to afford to do that. I was thinking of starting a foundation. To hide something inside for awhile, it's hard. You never feel proper. You feel guilty, you know. Reporter: He has carried that guilt even as rumors swirled. Ozzy Osbourne was on his deathbed. You know what you're proving. What? That you're not on your deathbed. Far from it. It's not easy to be so transparent. You've always been an open book. But something like this so I'm not going to be secret. I cannot walk around with it anymore because it's like I'm running out of excuses, you How, Sharon, have you been able to keep such a brave face through all of this? I have to be there for ozzy and for the family because if I break down and the dad -- no, no, can't, can't do it. You just can't do it. What do you want ozzy's fans to know? Oh, I feel better now due to the fact that I have Parkinson's and I just hope they hang around because I need them. Reporter: For ozzy his fans are in some ways giving him life. God bless you all Your fans aren't going to leave you. I hope not. They're my air. Why are you crying right now? Because it just means so much to him what he does. He loves to perform. It is the air that he breathes and this is the longest he's ever been home and it's time for him to get back on the road because he's driving me mad. So he really needs to get back out there. He really does. I just can't wait to get out and go on the road again. That's what's killing me. I need it. You know. That's my drug today. Don't give a crap. I survived that and I ain't going to go yet. I ain't going no go anywhere Alluding to his past because people heard about his lifestyle. The time I spent with him over the weekend in their home, just in the few hours that I was there, you could see the ebbs and flows that sometimes he would seem much better and sometimes not and he was talking about the numbness. He said, you're lying in bed and your arm fall as sleep or leg falls asleep. That's what he feels, that numbness but he is determined to return to -- Strengthens the whole system he feels it will fight it. Yes, to build up his immune system and feels that way he can continue on with the treatment. Doing by -- pilates and the way he talks about his fans, it gives him a purpose there. He has a great support system, Sharon and the kids. We'll talk to them. We'll talk to Sharon and also two of their children, Kelly and jack, in our next hour and also talk about what this last year has been for them because when a family member is diagnosed, everybody goes through it and this family has had their shares of challenges and also Dr. Ashton will join us in the next hour because so many are asking about Parkinson's and so many different forms of it.
