Adam Devine’s childhood accident continues to have a serious impact on his health.

The 41-year-old Workaholics star, who was struck by a cement truck at age 11, recently revealed that a doctor told him the injuries he sustained are still affecting his body — and may ultimately be life-threatening.

“It’s been a nightmare,” Devine said in an April 2 episode of the In Depth With Graham Bensinger podcast. “I have spasms all over. For a while,  the doctors told me I was dying—literally, within this last year.”

The Pitch Perfect star—who shares a 12-month-old son, Beau, with his wife, Chloe Bridges—was initially suspected to have Stiff Person Syndrome (SPS), a rare neurological disorder that causes severe muscle stiffness and spasms. He explained that the condition, which Celine Dion was diagnosed with in 2022, can become so extreme that it limits mobility entirely. In severe cases, he added, it can even affect the heart, making the muscles so rigid that the heart struggles to beat properly.

Adam Devine shared that he was initially diagnosed with Stiff Person Syndrome just a month before the birth of his son. However, doctors later retracted the diagnosis six months later. Despite the reversal, Devine still felt that something was wrong—he struggled to walk more than a few blocks before his muscles would become so tight he could no longer move.

After seeking a second opinion, it was confirmed he did not have SPS. Instead, doctors linked his muscle issues to the severe injuries he sustained in the childhood accident involving a cement truck.

Devine now believes that the intense workout routine he began three years ago—combining cycling and CrossFit—may have triggered the resurfacing of his symptoms.

“I think I just got so tight,” he said. “My body has all these things that are a little wonky and a little wrong with it, that I just sort of snapped.”

Over the years, the Modern Family alum has shared memories from his decades-old, near-fatal accident, including posting a throwback photo on Instagram of himself as a child recovering in the hospital.

“I couldn’t walk for two years and had to completely relearn how to walk,” he revealed in a post from 2017. “The nurses would always come in and have to adjust my legs, which were fully skin grafted and in traction. The pain was next level.”
