Jamie-Lynn Sigler Discusses Living Authentically With Relapsing MS

For years, actress Jamie-Lynn Sigler was quietly carrying a burden that few people around her fully understood. Best known for her role as Meadow Soprano on “The Sopranos,” Sigler was diagnosed with relapsing multiple sclerosis (RMS) at age 20 but kept her condition private for more than a decade.

Now, after living with RMS for 25 years, Sigler is speaking more openly than ever about the realities of chronic illness, the emotional toll of hiding symptoms and the power of self-advocacy. Through her memoir, public advocacy work and partnership with Novartis, she hopes other patients feel less alone navigating life with MS.

When Sigler first publicly disclosed her diagnosis after years of secrecy, she said several personal and emotional factors pushed her toward finally opening up.

“I couldn’t physically hide things anymore,” she said. “The strain and sort of the stress around that, especially in my work.… I had a child, and thinking about potentially, as he got older, asking him to lie for me, or even lie to him about the condition that I had.”

At the same time, she had developed a strong support system that reminded her that MS did not define her identity.

“I felt brave enough to share, even though it felt like the scariest thing in the world for me,” Sigler said. “But right on the other side of it was the beginning of a really beautiful journey.”

Even after revealing her diagnosis publicly, Sigler said it still took years before she felt comfortable discussing how deeply MS affected her day-to-day life.

“Even when I first said I had MS, it’s like, ‘But I’m fine and don’t worry and I’m great,’” she explained. “That is true, but I also understood, as I was gaining a relationship with the MS community, that they wanted to understand genuinely how it affected me and hear my authentic truth.”

Sigler said those conversations helped her recognize how important it can be for patients with chronic illnesses to feel seen and validated.

“When I feel seen and I have my experience validated, I feel more empowered to move forward,” she said. “You just need to sort of be acknowledged sometimes in your pain and what you're going through.”

One of the biggest lessons Sigler says she has learned over the years is that asking for help is not a weakness. For many people living with chronic illness, however, that can be incredibly difficult.

“You don’t want to ask for help because you want to still feel capable,” she said. “You want to still feel and seem independent.”

Sigler acknowledged that many patients fear that accommodations or support somehow mean they are “losing” to their disease. But over time, she reframed the way she thought about tools and assistance.

“I’ve learned that people like to be of service,” she said. “People like to help, and it’s really not that big of a deal — little adjustments to make your life easier.”

That mindset shift has helped her become more open about advocating for herself professionally and personally. She also realized that many others with MS were quietly hiding their diagnoses too.

“One of the things that caught me the most by surprise when I came out about having MS was so many people from all walks of life saying, ‘It’s a secret for me too,’” Sigler said. “‘I’m not telling my family, I’m not telling my friends, I’m not telling my place of work.’”

She believes many people with invisible illnesses worry about being judged or limited by others, but said secrecy can also become emotionally exhausting.

“For me, keeping it secret for so long was truly a physical and emotional weight,” she said.

As part of her advocacy work with Novartis, Sigler has also focused on helping patients feel more informed and empowered when making treatment decisions. She currently takes Kesimpta (ofatumumab) for her RMS after discussing options with her MS specialist.

“Being able to have that autonomy, to be able to have that independence, is incredibly important, especially when dealing with a chronic illness,” she said.

To help other patients navigate those conversations, Sigler helped cocreate resources available through TreatmentDecisionGuide.com and ReframingMS.com. The tools encourage patients to ask detailed questions about treatment goals, risks, lifestyle considerations and long-term plans.

“What I’ve learned over time is…information makes me feel like I have more control,” Sigler said. “It makes me feel like I understand more about what’s happening in my body, so I can make better choices.”

Ultimately, Sigler hopes newly diagnosed patients understand they do not have to navigate MS alone.

“We all carry pain. We all have things and obstacles and challenges in life,” she said. “Invite people in on your journey, and it will make it a lot easier for you.”
