Selma Blair's MS Advocacy and Personal Struggle.

Selma Blair urged her friend and former co-star Christina Applegate to get tested for multiple sclerosis (MS) after she experienced tingling in her feet. Applegate was eventually diagnosed with MS in 2021 and credits Blair with helping her get an early diagnosis. Blair, who lived with undiagnosed MS for 40 years, has become an advocate for people with disabilities and chronicled her experiences in the 2021 documentary "Introducing, Selma Blair." Despite her health challenges, Blair has not ruled out a return to acting.
