Start a
headache diary. Write down the time the
headache started, how long it lasted, what you did to try and treat it (meds, heat, cold...), anything you think may have triggered the headache, what type of pain the headache was (throbbing, puslating, ice pick, tight...), where the pain was located and how bad the pain was on a 1-10 scale.
Good luck... of and few days ago I believe a dr here on med help posted some info on headaches/migranes...
