A headache is a condition of pain in the head; sometimes neck or upper back pain may also be interpreted as a headache. It ranks amongst the most common local pain complaints.
Headaches have a wide variety of causes, ranging from eye strain, sinusitis, migraine and tension to life-threatening conditions such as encephalitis, meningitis, cerebral aneurysms, and brain tumors (although more than 95% of headaches are not life-threatening). When the headache occurs in conjunction with a head injury the cause is usually quite evident; however, many causes are more unclear.
The most common type of headache is a tension headache which may be caused by posture. Some experience headaches when dehydrated, or suffering from caffeine withdrawal symptoms. Headaches may also be caused in some people by certain foods, such as peanuts, or food additives, such as tartrazine. They may also be caused by fumes, such as from a faulty heating boiler or from vehicles.
Treatment of 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, usually triptans. It may be possible to relate the occurrence of a headache to the consumption of a particular food, which can then be avoided.
