See your physician: These symptoms may represent sinus issues, a specific kind of headache (migraine) or other neurological condition. Your friend should keep a log of the location, timing, duration, characteristic, and intensity of these episodes and take the log to his physician. He might be referred to a neurologist or ENT physician. http://www.nlm.nih.gov/medlineplus/ency/article/000647.htm
