“Dan” was a very successful trader at a major brokerage firm. The job required long hours entertaining clients at night and was very stressful. Dan began to have daily migraine headaches, with both sensitivity to light and sound (photophobia and phonophobia). When he should have been at the trading desk, Dan was forced to escape to a private office and take long naps; he just could not keep up with the requirements of the job. Dan applied for benefits on his own, which were granted.
