Christina Applegate and More Stars Battling Multiple Sclerosis

After learning her diagnosis in 2018, Blair said that she was experiencing an “exacerbation” of her symptoms, meaning they were worsening.

“I am disabled,” she wrote via Instagram at the time. “I fall sometimes. I drop things. My memory is foggy. And my left side is asking for directions from a broken gps. But we are doing it. And I laugh and I don’t know exactly what I will do precisely but I will do my best.”

While battling MS, she also joined the cast of Dancing With the Stars in 2022, telling Us Weekly that she was “excited for camaraderie” and for “support” from the other competitors. Two years later, she opened up about being in remission.

“I hurt all the time,” Blair said in a January 2024 Instagram video, noting that aging is painful for everyone. “I say that only for you people that hurt also. Like I get it.”

Blair explained that it’s “hard to stretch” because of Ehlers-Danlos syndrome, which affects connective tissues. “The Ehlers-Danlos will make me really, really stiff because I’ll pull my muscles too easily,” she said. “So I get some injuries, but this is nothing that’s like horrible, scary stuff or anything. It’s just like one of those extra things that turns into a chronic thing and you have to watch.”
