Key Highlights:
- Christina Applegate shared that her debilitating physical symptoms are intensifying after learning she was misdiagnosed with multiple sclerosis (MS).
- Speaking on her MeSsy podcast with co-host Jamie-Lynn Sigler, Applegate revealed she is now back at square one, requiring a walker next to her bed due to excruciating pain and limited mobility.
- Medical experts note that MS misdiagnosis can occur in roughly 20 percent of cases because there is no single diagnostic test for the neurological disorder.
Christina Applegate has opened up about her deteriorating health after receiving the shocking news that her prior multiple sclerosis (MS) diagnosis was incorrect. The 54-year-old actor, widely known for her roles in Anchorman and Dead to Me, first disclosed that she had MS in 2021 after enduring persistent numbness in her lower extremities. Recalling those initial signs during a previous appearance on the Conan O’Brien Needs a Friend podcast, Applegate detailed the progression: “My toes weren’t feeling right. Eventually, over those months it grew from my toes to my ankles… from my knees down.”
She further noted at the time: “I was losing balance [and] the pain was extraordinary. When I say numb it’s numb but it hurts.”
Confronting a Shocking Misdiagnosis
Despite years of navigating life under the assumption that she was fighting MS, Applegate disclosed that physicians recently determined she does not actually have the autoimmune disorder. During an episode of her podcast MeSsy, which she co-hosts with actor Jamie-Lynn Sigler to chronicle their journeys with chronic illness, Applegate described the moment her medical team reversed the diagnosis on October 20.
“She came into my room and said, ‘Congratulations, you don’t have MS’,”
Applegate shared, expressing the frustration and uncertainty that followed the revelation. “I was, like, not happy at all. Everybody else was so happy.”
Clarifying that the correction provided no immediate relief, she told her co-host: “You don’t get misdiagnosed and then all of the sudden I’m better. I haven’t gotten better, Jamie! If anything, I’ve gotten worse. So I’m back at square one where I don’t know what’s going on with me.”
Worsening Symptoms and Daily Mobility Struggles
Rather than bringing answers or relief, the removal of the MS label has left Applegate facing an unnamed condition that continues to compromise her day-to-day functionality. In a recent update on the podcast, she revealed that the physical toll has escalated to the point where simple movements require significant effort, leaving her hospitalized at times and relying on assistive equipment.

“It took me 10 minutes to be able to move off my pillow and get out of the bed and stand up, at which point I almost couldn’t walk to the bathroom,”
Applegate said. She explained that she now must keep a walker stationed beside her bed to navigate her home. “I don’t know what’s going on,”
she added. “This is what I’m still living with. And I never had that before. I was able to sit up and stuff.”
The progression has introduced new barriers that she has not dealt with previously: “So this is what I said when things are getting worse or they’re just new. Something new is happening. So it took 10 minutes just to sit my head up, just to move without excruciating pain and weakness.”
Why This Matters
Multiple sclerosis is an incurable neurological condition impacting the central nervous system, including the brain and spinal cord. As outlined by medical authorities, including the NHS, symptoms vary widely across patients but frequently manifest as chronic fatigue, vision impairment, loss of balance, muscle spasms, localized numbness, and cognitive disruptions. While therapies exist to mitigate flare-ups and manage symptoms, identifying the disease remains complex.
Applegate’s experience highlights the substantial diagnostic hurdles associated with complex neurological disorders. Dr. Marwa Kaisey, a neurologist from the Cedars-Sinai Medical Center department of neurology, joined the MeSsy podcast to address the issue, noting that misdiagnosis happens in nearly 20 percent of suspected MS cases. Emphasizing the absence of a definitive, stand-alone diagnostic tool, Dr. Kaisey explained: “We don’t have one single test for MS. 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.”
For patients like Applegate, an overturned diagnosis underscores the prolonged struggle of identifying rare or overlapping neurological illnesses without an obvious clinical roadmap.
Frequently Asked Questions
Why was Christina Applegate’s initial diagnosis revoked?
Applegate was informed by her physician that further evaluations showed she does not meet the criteria for multiple sclerosis. Diagnosing MS relies on a complex checklist of neurological symptoms and imaging rather than a single definitive test, which can occasionally lead to misdiagnosis.
What symptoms is Christina Applegate currently experiencing?
Applegate continues to battle severe weakness, extraordinary pain, balance loss, and numbness that originally began in her toes and expanded upward. Her mobility has decreased significantly, requiring up to 10 minutes simply to sit up and necessitating the use of a walker to move around her home.
How common is a multiple sclerosis misdiagnosis?
According to Dr. Marwa Kaisey of the Cedars-Sinai Medical Center department of neurology, misdiagnoses are relatively common, with an estimated 20 percent of individuals diagnosed with MS ultimately turning out to have a different underlying condition.
