Imagine the Strangest Medical News of the Year
Imagine fighting a disease for five years. Imagine it taking your mobility, your career, your daily life. Now imagine your doctor walking in and saying, “Congratulations, you don’t have it.” You would expect tears of joy. Relief. Maybe a laugh you have been holding in since 2021.
Christina Applegate heard those exact words this month. And she cried, not from happiness, but from grief.
“She came into my room and said, ‘Congratulations, you don’t have MS,’” the 54-year-old actress recalled through tears on the October 20 episode of her MeSsy podcast. “I was, like, not happy at all. Everybody else was so happy.”
That one sentence flipped five years of her life upside down. And it is the strangest, saddest kind of medical news: the kind that leaves you with less than you started with. It is also the latest of the internet’s viral celebrity stories that nobody saw coming.
The Podcast Episode Nobody Was Ready For
Applegate hosts MeSsy with her friend Jamie-Lynn Sigler, and the two have spent years talking openly about living with multiple sclerosis. Sigler has MS. For a long time, everyone believed Applegate did too.

She announced her diagnosis in August 2021. It derailed her career mid-stream. She finished out Netflix’s Dead to Me, one of her last big on-screen projects, while the disease was visibly affecting her ability to perform. Then she stepped away from acting almost entirely. After a seven-month hiatus, during which she spent several months in the hospital earlier this year, she returned to the podcast on October 20.
Listeners expected a health update. They did not expect this: during her time away, her doctor had told her she had been misdiagnosed the whole time. The symptoms were real. The wheelchair she relies on to get around is real. The MS, according to new testing, is not.
“You don’t get misdiagnosed and then all of the sudden I’m better,” she said, the emotion raw in her voice. “I haven’t gotten better, Jamie! If anything, I’ve gotten worse in some ways. So I’m back at square one where I don’t know what’s going on with me.”
Back at square one. Five years of building a life around a diagnosis, gone, with nothing to replace it.
Why Good News Can Feel Like a Loss
Here is the part that confuses people who have never lived with a serious chronic illness. A diagnosis, even a terrible one, is a map. It tells you what is happening, what might happen next, which treatments exist, which doctors to see. It gives your suffering a name.
Applegate lost the map. As Gina Moffa, a grief and trauma therapist in New York, told USA Today: on paper, a cleared diagnosis looks like good news, but a diagnosis “gives you something to hold and some sense of direction.” When that label is taken away, Moffa explained, “you’re still struggling and suffering, and you’ve lost the map.”
The actress still cannot walk from her car into a doctor’s office. She still uses a wheelchair for basic mobility. Her symptoms have not improved at all since the news. If anything, they have progressed. So the doctor’s “congratulations” answered none of the questions that actually matter: What is wrong with me? Why did this happen? What do I do now?

Then there is the identity piece, which might be the hardest part of all. Applegate had become, in her words, the “poster child for MS.” She built a community, a podcast, a public mission around that shared experience with Sigler and millions of listeners. Now she carries guilt about the platform she stood on. She admitted she felt like she had let everybody down. People had looked to her, and she worries the whole thing was built on a mistake she never chose to make.
This Happens More Than You Think
The most startling part of the MeSsy episode might not have been Applegate’s story at all. It was the doctor who joined them.
Dr. Marwa Kaisey, an associate professor of neurology at Cedars-Sinai Medical Center, appeared on the podcast and said MS misdiagnoses are “fairly common.” The number she gave is jarring: nearly 20 percent of people diagnosed with multiple sclerosis turn out not to have it. Almost one in five. And the majority of those people were on medication to treat a disease they never had, LADbible reported.
Why? Because there is no single definitive test for MS. As Kaisey put it: “It’s not like we have something like a pregnancy test that says, ‘Yes. You have it.’ ‘No. You don’t.’ It’s a list of criteria.” New technology and updated criteria caught Applegate’s case, but countless others are still out there taking the wrong drugs for the wrong disease.
Applegate says she has “every single” symptom of someone with MS. “Something else is going on,” she concluded. The next phase of her journey is what she called “an online investigation that my doctors are going to be getting into,” trying to trace back to 2021 and figure out what was actually happening all along.
What She Lost, and What Comes Next
It is easy to reduce this to a medical curiosity. It is not one. Applegate gave up acting, her life’s work, because of a diagnosis she now knows was wrong. She spent years adjusting her entire existence around a disease she did not have. She published a memoir this year, You with the Sad Eyes, a New York Times bestseller about resilience and self-acceptance, written from inside a story she believed was hers.

Now she has to rewrite that story with no ending in sight.
But here is what I keep coming back to: her honesty. It would have been so easy to come on the podcast, smile, and tell a tidy story about a miracle recovery that never happened. Instead she told the truth, which is messier and sadder and far more human. She said she was not happy. She said she felt like a failure to the community that trusted her. She let people see the part of illness that has nothing to do with medicine: the identity, the fear, the starting over at 54 with an empty wheelchair and a full set of unanswered questions.
The internet is famous for demanding clean narratives. Good news, bad news, done. Applegate just handed it something much more complicated, and in doing so, she might have done more for people with mysterious illnesses than any diagnosis ever could. Read more Viral stories from VIDX Trends.
Whatever is actually wrong with her, she deserves an answer. Until then, she is doing the bravest thing a public person can do: sitting in the unknown, on the record, and refusing to pretend it is anything other than what it is.
