AceShowbiz - Adam Devine, known for his roles in "Pitch Perfect" and "Modern Family," revealed a harrowing journey from a near-fatal childhood accident to recently being told by doctors he might be dying.

As a child, Devine was hit by a 42-ton cement truck while crossing a street, rendering him unable to walk for two years and resulting in dozens of surgeries. Though he eventually recovered and pursued a career in comedy, the long-term impact of the accident caught up with him.

In an emotional appearance on the "In Depth With Graham Bensinger" podcast, Devine recounted the severe spasms and chronic pain that led medical experts to initially diagnose him with Stiff Person Syndrome (SPS), a rare neurological disorder.

"They told me that I had that literally a month before my son, Beau, was born," Devine shared. The prognosis was grim, with doctors warning the condition would cut his life short.

However, upon seeking a second opinion from the very expert who coined the term SPS, it was revealed that Devine's symptoms were rooted in his childhood accident. Devine explained, "The spasms are a little unexplainable, but it could just be [that] you got so tight that your body doesn't know what to do with it so you're misfiring a little bit."

The unexpected turn in his diagnosis came as Devine was coping with the challenges of new parenthood. Despite the relief of not having SPS, his health remained in a precarious state, exacerbated by his rigorous cycling and CrossFit routines.

"I think I just got so tight and so tightly wound, and my body has all these things that are a little wonky and a little wrong with it that I just sort of snapped," Devine said.

While dishing on how his younger self was coping with this ordeal as a child, Devine shed light on how his unique comedic voice emerged. Wheelchair-bound as a child, he started calling a local radio station to perform impressions in exchange for concert tickets, sparking his passion for comedy.

This determination eventually led Devine to Los Angeles, where he found success in the entertainment industry.

Reflecting on his journey, Devine emphasized that his symptoms, while still partly "unexplainable," have not diminished his resolve to live a full and creative life. "The best I've been now for the past three years," he stated, clinging to hope brought by recent stem cell treatments.

Devine continues to bring laughter to his audiences. He stars in HBO's "The Righteous Gemstones" and voices characters in upcoming animated features.
