News at Eleven: [Kenneth Heaton] found that Shakespeare's

portrayal of symptoms such as dizziness/faintness, and blunted or heightened sensitivity to touch and pain in characters expressing profound emotions was significantly more common than in works by other authors of the time.

Vertigo/giddiness/dizziness is expressed by five male characters in "Taming of the Shrew," "Romeo and Juliet," "Henry VI" part 1, "Cymbeline" and "Troilus and Cressida." The nearest approximation in contemporaries' works was one incident in John Marston's "The Malcontent."
