Whiplash injuries are often treated as purely musculoskeletal issues, but the story doesn’t end with muscles and joints. Hidden within the cervical spine is a critical neural pathway that may help explain lingering symptoms after trauma—the vagus nerve. When the neck is injured, this vital nerve can be disrupted, potentially affecting the body’s ability to regulate stress, recovery, and internal balance. Understanding this connection offers a deeper look at why some whiplash cases don’t resolve as expected—and what might truly be driving persistent post-injury symptoms.
