I think you have migraine headche.. It is Not unusual to aura before a migrain attack.... your symptoms associated with the eyes which you get before you have headache is an aura.. you can take Tylenol, or Aspirin( if you can tolerate it) or ibuprofen(Advil, Motrin) etc... if these non-prescription drugs don't seem to work.. then go and see a doctor.. you might need some prescipton drugs... ergotamine or sumatriptan.. If you are in Korea.. I don't know whether these are available.. or not.. but you can certainly talk to your doctor or pharmacist.. meanwhile.. if you have migraine attack..try to rest.. and try to find what is triggering your headache.. and the best way is to avoid that triggering factors.
