Treatment
of an uncomplicated headache is usually symptomatic with over-the-counter painkillers
such as aspirin, paracetamol (acetaminophen), or ibuprofen, although some specific
forms of headaches (e.g., migraines) may demand other, more suitable treatment.
It may be possible to relate the occurrence of a headache to other particular
triggers (such as stress or particular foods), which can then be avoided.(1)
