Headache
Headaches are pains and discomfort experienced around the head and neck areas, as a result of either the contraction of muscles in each of these parts or the constriction of the blood vessels in each. The first situation results in tension headache, and is usually due to emotional and physical stress, poor posture, eye strain, smoking, and drinking alcohol. The second situation results in migraine headache, and is caused by a prolonged muscle tension, stress, lack of sleep, smoking, drinking alcohol, as well as simply inheriting the tendency to develop migraines. Headaches of either type may also be due to the use of certain medication, or exposure to environmental elements such as radiation or pollution.
Headaches may heal or pass by itself with rest and relaxation even without medication; but they may also be treated with over-the-counter drugs or be consulted to the doctor for examination and medication.
