As we reported last week, Osbourne canceled his planned European tour because new medication he is on causes him to have dry mouth and he therefore can not sing. (see story).  Now Ozzy has gone on the record with MTV and let the cat out of the bag about his ailment. 

Turns out it wasn�t Parkinson�s, multiple sclerosis, delirium tremens or any number of ailments that the rock star was rumored to have. In the end it was a hereditary condition. 

Ozzy has a Boston neurological specialist to thank for finally discovering the cause of his shakes and now with his new medication the terrible tremors are gone. MTV reports that �, he's already looking, sounding and walking better than he has in years.� 

Ozzy spoke with MTV last week and filled them in on his ailment. "It turns out that it's a hereditary thing that I have from my mother's side of the family," Ozzy said in the interview. "This guy in Boston fixed me great. He's taken me off all the medication that I was on. I'm taking one medication now for this tremor.

"And [now], I haven't got the tremor."

"I can't tell you how wonderful I feel,� Ozzy said. �Not wonderful in the respect of [being] 'stoned.' I'm not stoned. [But] with [just] a pill, it was like somebody turned the bad switch off. I feel good again." 

The irony comes that the answer to Ozzy�s ailment was right in front of his face the whole time. It is a hereditary condition that effected members of his mother�s family, including Ozzy�s mum. For some reason Ozzy never noticed it. 

Ozzy has been battling the tremors since his early 20�s but they have grown steadily worst over the years. No amount of treatment and testing could find the source or the problem or relieve the tremors but now Ozzy knows the answer to both problems.
