British rocker Ozzy Osbourne says he's relieved his debilitating body tremors are from a genetic syndrome -- not his lifetime of drug abuse.
Osbourne, 56, said doctors ruled out Parkinson's disease despite tremors that were "practically destroying my life" as well as multiple sclerosis.
Once doctors diagnosed Parkin Syndrome, Osbourne said his sister told him his mother, aunt and grandmother suffered from the same problem.
"I'm like, 'Thanks for (expletive) telling me'. Me walking around thinking I've got some drug paralysis," Osbourne said.
