South Korean actor Lee Dong-gun received a life-altering diagnosis of ankylosing spondylitis while filming an episode of My Little Old Boy, a popular SBS television show. The 45-year-old star had been experiencing severe and ongoing inflammation in his right eye, prompting a hospital visit that revealed the underlying condition.
Doctors linked his symptoms to a form of arthritis that causes inflammation in the spine and pelvis, potentially leading to reduced flexibility and possible fusion of bones over time.
