Hysteria was widely discussed in the medical literature of the 19th century. Women considered to be suffering from it exhibited a wide array of symptoms including faintness, nervousness, sexual desire, insomnia, fluid retention, heaviness in abdomen, muscle spasm, shortness of breath, irritability, loss of appetite for food or sex, and "a tendency to cause trouble".
Sexual frustration -aka "Female Hysteria" can lead to irritability, muscle spasms, and insomnia among other symptoms. What to do with a Victorian woman in such a state? Send her to a doctor for professional pelvic massage. Victorian men paid doctors to to "treat" their wives with "hysterical paroxysm" -aka orgasm. A Dr. finding this to be tedious (?!) invented a machine=first vibrator.
