A Young Coworker Said He Experienced These Symptoms Yesterday In

A young coworker said he experienced these symptoms yesterday in the early evening. A severe headache (worst he has ever experienced--she said worst than a migrane), slight nausea and cold sweats. He said his head felt like it was burning up, but there was no fever when he took his temperature. This occurred 30 minutes after he took a medication that he is taking on an as needed basis. He is not experiencing them now, but has a constant cough.
