The past few years have been tough on Ozzy Osbourne‘s health, as the 71-year-old rock singer has been plagued by repeated postponements of his worldwide No More Tours 2 Tour to recover from a fall he suffered last winter which required surgery. While the recovery from surgery has surely been difficult, Osbourne revealed on Tuesday that he’s had more serious health issues to deal with, as he announced that he’s been diagnosed with Parkinson’s Disease.

In an interview which aired on Good Morning America, Ozzy and his wife/manager Sharon Osbourne opened up about the challenges of dealing with the incurable disease which greatly affects the body’s nervous system. Osborne discovered he had a “mild form” of the disease following last year’s surgery.

“It’s Parkin 2,” a very emotional Sharon added when Ozzy attempts to describe his illness. “Which is a form of Parkinson’s and it is… there are 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. It’s like you have a good day, a good day, and then a really bad day.”

A soft-spoken Ozzy continued in discussing how nerve damage and the 2019 surgery has resulted in numbness and unusual sensations in his arms and legs.

Ozzy’s initial fall which took place after his Ozzfest performance on New Year’s Eve 2018 at Los Angeles’ The Forum, was the incident that forced the famous hard rock singer to postpone all of his 2019 tour dates. Prior to that, the 70-year-old was hospitalized due to complications from the flu—the same illness which led to the postponement of his U.K. and European shows in January 2019. As of Tuesday, Osbourne’s 2020 tour schedule is set to begin on May 27th with a show at State Farm Arena in Atlanta, GA.

Sharon also revealed she and her husband will travel to Switzerland to find new, innovative ways and answers to slow down the process of the disease and build his immune system.

“It’s time for him to get back on the road because he’s driving me mad,” Sharon continued. “So he really needs to get back out there.
