Headaches are one of the most common health problems in the world. In fact, every human being would have experienced some kind of headache. Headaches may range from a mild, infrequent, dull ache, to an excruciating, persistent, debilitating condition, which may make it difficult for the person to carry out his or her normal life activities. Advancement in medicine and technology, in recent times has made it easy to diagnose the problem and provide a treatment for it.
What Causes Headaches?
Contrary to belief, it is not the brain that is affected due to headaches. The areas where the pain may originate may include; tissues surrounding the brain like, blood vessels and muscles of the face, neck and scalp, or the area of attachment at the base of the brain
Major Headache Types
Based on etiology, headaches are of two categories, primary and secondary. This classification helps doctors to distinguish between the different kinds of headaches and to arrive at the right treatment method.
A primary headache is one, which is not caused by a disease or a medical condition. The major types are migraine, tension and cluster headaches. Migraine- Also called neurovascular headache is caused by abnormalities in the blood vessels of the brain, scalp and facial tissues. Medical evidence strongly points to the influence of genetic factors in the etiology of migraine headaches. It may also be precipitated, by extrinsic factors like; food, weather changes, atmospheric pressure, stress and excessive sleep.
Treatment of migraine usually focuses on treating the cause, rather than using simple painkillers. Patients are encouraged to discover the factors that trigger migraine attacks, recognize warning signals, and make appropriate changes in life style to help them ward off an attack.
Tension, constitutes nearly 90 percent of the primary type of headache. They usually occur as a dull and aching pain and could sometimes turn severe. They may be intermittent or chronic, depending on their severity and frequency. Both types are characterized by pain in the forehead, temples, back or neck and are caused by the contraction of the muscles of the neck and head. Although, stress is a major cause for this type of headache, it may be triggered by other factors like outside temperature, poor posture and sleeping habits, strain to the eye or depression and anxiety.
It usually involves simple, over-the –counter drugs and making life style changes. For patients in whom, the headache is caused by insomnia, fatigue and extreme stress, physicians may advice anti-depressants, though the person may not be suffering from depression.
Considered the most painful of all the headaches; they are acute and occur without warning. The patient experiences excruciating, penetrating pain mostly around the eye and feels restless and agitated. Other symptoms include, swelling in eyelids, watery eyes, runny nose and facial sweating.
