Legally Blonde actress Selma Blair revealed her multiple sclerosis diagnosis on Instagram in 2018. She told CBS Mornings that she started feeling sick in her 20s before a doctor told her she had optic neuritis — one of the common symptoms of MS.

She also experienced headaches and fevers, but Blair only received an official diagnosis when she was in her 40s.

“I was surprised, but then I was like ‘Oh of course,’ and when the doctor said the first night, ‘You’ve had this at least 25, 30 years, at least,’ I was happy. I needed it,” she continued. “So to find that out and say, ‘Oh, there’s a story I can put together’ — it was life-changing.”
