A 39-year-old female presents to your office with a 3-year history of headaches. They occur once or twice per week, lasting several hours. The headaches are throbbing and are usually on her left side. During these episodes, the patient is incapacitated and must lie down in a dark room for several hours. She is sensitive to light during the episodes and cannot move because of the pain. She is often nauseated and has vomited on several occasions. Medical history is significant for hypothyroidism, for which she takes levothyroxine (Synthroid). Her physical examination is unremarkable, however the patient endorses another similar headache and begins vomiting near the end of the examination. What is the appropriate next step in managing this patient?
