Christina Applegate Says It Takes Her '10 Minutes' to Get Out of Bed Amid MS Misdiagnosis: 'I Don't Know What's Going On'

Christina Applegate opened up about how much her ongoing health problems are affecting her everyday life.

In the latest episode of "MeSsy," the podcast she hosts with Jamie-Lynn Sigler, the actress revealed that it recently takes her 10 minutes to get out of bed.

Her latest update comes just a week after Applegate shared that her doctor told her she did not have multiple sclerosis (MS), despite having believed for years that she was living with the condition.

The View from the Top star described the difficulty she now experiences when trying to stand up and move around her home.

"I actually timed it today. It took me 10 minutes to be able to move off my pillow and get out of the bed and stand up, at which point I almost couldn't walk to the bathroom," she said.

Applegate also revealed that she now keeps a walker beside her bed to help her move around because of her mobility issues.

What makes this particularly difficult is that she says this wasn't always the case. The 54-year-old used to be able to sit up without struggling like this, but her condition has changed. "I don't know what's going on. You know, this is what I'm still living with," she shared.

The Don't Tell Mom the Babysitter's Dead star is still dealing with the same health problems without knowing what is causing them.

"You don't get misdiagnosed and then all of a sudden I'm better," she said on the podcast. "I haven't gotten better... If anything, I’ve gotten worse in some ways. So I’m back at square one, that I don’t know what’s going on with me."

Doctors can sometimes find it difficult to diagnose multiple sclerosis (MS) because there isn't one single test that can confirm the condition.

During Part 2 of the podcast, neurologist Dr. Marwa Kaisey explained that doctors have to look at a person's symptoms, medical history and test results before deciding whether they have MS. They also need to rule out other conditions that could be causing similar symptoms.

She added that nearly one in five people diagnosed with MS may not actually have the disease.

Despite the change in her diagnosis, Applegate has no intention of distancing herself from people living with MS. "I love this community, man," she said.

"I'm going to still be an MS warrior no matter what because of championing for the people that I love," the Surviving Christmas star said.
