What does Seq often experience as a result of the stress in his life in the novel, Where the Dead Sit Talking?

The frequent headaches that Sequoyah suffers both represent and manifest the virtually constant stress he is under, as a result of his being abandoned by his parents, somewhat lost within the foster care system (until he arrives at the home of the Troutts) and, to a significant degree, lost in terms of his sense of self. They are a literal, physical manifestation of his inner, emotional pain.
