Jamie-Lynn Sigler Marks 10 Years Battling MS

It's been a decade since Jamie-Lynn Sigler publicly revealed her multiple sclerosis diagnosis, which she had kept secret for 15 years for fear she'd never work in Hollywood again.

The 44-year-old Sopranos alum - who uses a mobility scooter to get around - now regrets the lengths she went to in order to conceal her limp, bouts of incontinence and pain from the industry and the world at large.

'What struck me the most was the outpouring of support from the MS community,' Sigler said in her Us Weekly cover story.

'I realized, "Oh, I have robbed myself of this tribe, of these people who see me. And I'm not alone anymore."'

The two-time Actor Award winner added: 'It's wild to think that I'm the most settled and confident I've ever been, despite living in a disabled body.'

Sigler previously felt like she 'was always acting' and 'everything was a lie and for show' while hiding her flare-ups from the autoimmune disease of the central nervous system.

'I finally had a lead in this high-profile pilot, and it was everything I wanted, but it was a terrible experience for me because I was so terrified everyone was going to find out,' the Man in the Window actress recalled.

'The relief I had [when it wasn't picked up] was the opposite of what anybody should feel. I was like, "Thank God, I'm still safe." My reps didn't even know at the time.'

However, Sigler did disclose her secret health battle to her late onscreen father James Gandolfini, which she called a 'game-changer' while shooting her breakout role as rebellious teenager Meadow in the hit HBO mob drama from 1999-2007.
