Actress Christina Applegate says she was misdiagnosed with multiple sclerosis (MS), a neurological and autoimmune disorder.

"It's hard to say that [my doctor] came into my room and she said, 'Congratulations! You don't have MS,'" Applegate said on Tuesday's episode of MeSsY, her podcast with co-host Jamie Lynn Sigler.

Applegate first revealed on social media in 2021 that she was diagnosed with MS. This is a developing story.
