• Selma Blair spoke about her early multiple sclerosis symptoms in a new Instagram post.
• Blair said she "couldn't feel the ground" and her leg was numb during a Christian Siriano show.
• Blair, 48, revealed her MS diagnosis in an October 2018 Instagram post.

Selma Blair experienced early multiple sclerosis symptoms while walking in a Christian Siriano fashion show.

Blair was first diagnosed with multiple sclerosis, or MS, in August 2018 and has since been candid about navigating the incurable disease. While the first symptoms of MS are often blurred or double vision, several symptoms can likely follow, including balance and coordination difficulty, muscle weakness, and numbness, among others.

Blair said in an Instagram caption that her left leg felt numb during Siriano's New York Fashion Week show in February 2018.

"3 years ago.," Blair, 48, wrote in the post. "My dearest two pals came to watch the Siriano show. I walked that day. In the show. Noticing for the first time, my leg was numb. When I first stepped out. I couldn't feel the ground or how to lift my left leg. My brain was trying to compute."

The actress described feeling "stunned" as she joined fellow celebrities like Danielle Brooks and Ashley Graham on the red-carpet runway.

"It hardly dampened my day though," Blair wrote. "Art and Carolyn shot these favorite frames of mine. In that incredible space in nyc. After the show was done. And what a show it was. The greats."

The "Cruel Intentions" star accompanied the message with four photos from the New York Fashion Week event.

Since revealing her diagnosis, Blair has regularly shared updates on her condition to her Instagram account.

According to People, Blair's illness has caused difficulties with her speech and ability to use her left leg fully, requiring her to use a cane to walk. She has undergone treatment, including a stem cell transplant and chemotherapy.

In May 2020, Blair shared a video of her walking in leg braces amid her ongoing MS battle.

Most recently, Blair revealed she was able to go horseback riding again after being forced to avoid the activity due to MS. She purchased a horse named Nibbles just before her diagnosis.

"When I bought Nibbles three years ago, it was my biggest investment in myself," Blair wrote in a caption posted late January. "A sober self with increasingly unremitting exhaustion. I couldn't feel my bum or left leg on my horse."

She said she experienced "proprioception issues, inability to sit still, spasms, twitches. Jerks. Dystonia increased."

"I just laughed and thought getting older is impossible! But it was ms and it got too big and I had to take a break until now," Blair wrote. "I am at the beginning. Still. And I cannot stop smiling. I cannot. When I am at the barn. I finally have the white unicorn I cannot believe is in my life and I want to rise to the occasion."
