Selma Blair shares painful health update: 'There is no bright light of glamour'

Selma Blair is continuing to be candid about her health struggles since revealing her multiple sclerosis diagnosis a little more than a year ago.

The actress shared a photo of herself curled up and posted a lengthy message to Instagram Tuesday about her pain .

"This is the thing. I feel sick. This is what happens. There is no bright light of glamour," Blair wrote. "It is long nights. Almost all nights. My muscles in my face and neck are in spasm. Or so tight I can’t even find a way to stretch. And I have been trying for three hours. On the ground stretching. I have had the stomach flu."

Her photo comes as a stark contrast from last year's Oscars week when she attended the 2019 Vanity Fair Oscar Party in a strapless Ralph & Russo gown and posed with a customized cane.

The 47-year-old mom shared her gratitude in being able to recover from things like an ankle sprain she suffered last week after taking a wrong step.

"And I am lucky on a million counts. I know. And I am still feeling alone and vulnerable and scared about the future as a single mom. I’m not dying any more than anyone. I am just hurting. It feels like I am just breaking down," Blair wrote. 

She also sympathized with others who are feeling ill.

"This is just me to you. In the early hours of the morning. Cause I don’t know what else to do and I want so much to do better. May the silver lining surround us all. And guide us out of the darkest," Blair wrote. "Thank you all for being the biggest loves. I am in a slow time. I need to recover. I want to recover. And I don’t know what that even really means."

Selma Blair on undergoing 'aggressive' chemotherapy to treat MS: I was 'out of options'

The "Cruel Intentions" actress has been open about her health struggles.

Last year, she shared she would be undergoing "aggressive" chemotherapy and stem cell transplant to help alleviate some of the pain and ailments from her multiple sclerosis diagnosis as her other treatments hadn't been working.

In September, Blair shared bold photos sporting her shaved head.

"My hair is still not growing in … I never minded hair loss or any of those things that would be ego-involved," Blair said. "My dream was to lie next to my son at night and be there as long as he needs me and hopefully do something for people. I've heard so much from people with chronic diseases or MS, and they're scared and they don't know when it's going to get worse."
