Headaches not only affect people of all ages, but they can also range in severity and can be linked to other symptoms or causes. The key to effective headache management is to discover individual-specific "triggers" that set off the headache so that they can be negated or avoided when possible. However, it may take time to discover the trigger, and it may take a lot of time, trial, and error.

Causes
The specific cause of a headache is largely unknown, but is thought to be caused by chemical changes in the nerves and blood vessels of the affected area. Each person has his or her own "trigger" that can set off an episode, and are usually specific to that person. Some common triggers for headaches include:
-- Allergic Purpura
-- Certain medications and potential side effects
-- Irregular sleep patterns and habits
-- Skipping meals or malnutrition
-- Dehydration
-- Severe stress
-- Repercussions of minor head injuries from the past
-- Using the computer or watching the TV excessively
-- Vision problems and/or light sensitivity
-- Changes in hormone levels, such as during menstruation
-- Taking long trips in cars or buses
-- Intake of stimulants and depressants, such as alcohol or caffeine
-- Eating certain foods, such as MSG, fried foods or preservatives
