Sharon Stone has revealed she was once "hit from behind" and "didn't really know" what happened until a decade later.

The 68-year-old actress has recalled the horrifying assault by an unnamed perpetrator, and it was "years later" when a doctor found evidence of a "felony" during a medical exam.

Speaking on The Person Who Believed In Me podcast, Sharon said: "I don't know how much I can tell about this. I was hit from behind.

"I didn't really know until 10 years later what had happened to me because I woke up. I was unconscious on the floor. The two couches were sideways. The coffee table was all over the place.

"It was sort of upside down. Everything that had been on the coffee table was all over the floor and I didn't know how I got there."

It was a decade later until a visit to the doctors brought the incident to her attention.

She explained: "I went to a clinic because I was having a lot of problems with the back of my neck and my shoulders were so sore and I went to a neck and spine clinic in Marina Del Rey and they had given me propofol and they'd done a lot of X-rays of my front and back and all this stuff.

"They were going to do some kind of injections into what they thought was arthritis in my neck and shoulders, and they had done all these preliminary x-rays of my thoracic rib cage and my neck and my shoulders and my spine and the doctor came in and he's like, 'We're not going to be able to do this surgery.'

"I was like, 'I don't know what you're talking about.' And he's like, 'Your thoracic rib cage is all fractured and scarred back together. It's clear that you were attacked and that what happened to you was a felony.' "

Although the podcast host and CBS correspondent David Begnaud asked who attacked Stone, she refused to reveal the name "publicly".

She responded: "I am not going to say publicly, but I am going to say that we did report and we did do everything."

Meanwhile, she noted that despite having "the opportunity to press charges", she decided against it "because it had been a decade and because I'm a public figure".

The Basic Instinct actress added that despite believing she had enough "circumstantial evidence to make a case", she also "did not want that to be my legacy".

When asked if she believed the incident was domestic violence, Sharon replied: "I'm not at liberty to say."
