Ozzy Osbourne recently had to cancel a string of dates on his farewell tour due to emergency surgery and infections. At the time, it wasn't clear exactly what Osbourne's health issues were, but he's recently elaborated he was suffering from three staph infections on his thumb with one of the infections spread to his middle finger. A staph infection occurs when germs on a person's skin make it into their blood stream, and it could potentially turn deadly.
Ozzy has now taken to Instagram to tell everyone he's doing way better and he's excited for the coming Ozzfest festival.
