Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. In case you have pulsating episodes of headache and increase with any sort of movements, associated with nausea, photo phobia and only part of head is involved. It is a most probably the Migrainous headache. You need to consult a neurologist or a general physician for proper diagnosis. Also check your blood pressure regularly for two to three days, sometimes consistent high blood pressure may precipitate in the form of terrible headaches. Hope I have answered your query. Let me know if I can assist you further.
