An allergy headache is one that is triggered by an allergic reaction to specific substances, foods or environmental changes called allergens. An allergy is also known as atopy and affects the immune system adversely. Allergy headaches range from moderate to severe in terms of frequency and can vary in duration. They can cause a great deal of discomfort and agony to the patient suffering from the headache and disrupt the normal functioning of daily life.

Patients suffering from allergy headaches have a sensitive nervous system and the presence of an allergen can result in reactions of the respiratory system and nasal tract causing congestion, sneezing and dripping of the nose.

Types of Allergy headache:

Sinus Headache: Sinuses are air filled cavities in the head that join the nose and head through tiny openings. During an allergy attack these sinuses become infected and inflamed in the passages behind the eyes, cheeks and nose causing congestion. This causes a profound pain in the forehead, front of the face and behind the eyes.

Cluster Headache: Also known as suicide headache, this type of headache is known for its severe intensity of pain. It is likely to affect more women than men and can be triggered by an allergy. Cluster headaches can last from a few hours to weeks and even months and can relapse after a brief period of relief.

Migraine: Migraines are accompanied by pounding pain, vomiting, blurring of vision and increased sensitivity to light, sound and smell.They can also be triggered by an allergic reaction as individuals susceptible to migraine attacks have a sensitive nervous system.

Causes of Allergy Headache:

Food Allergy: In order to combat allergy headache, it is essential for you to avoid foods you are allergic to. You can maintain a diary whenever the headache occurs and keep track of the foods you have eaten prior to the headache as they might be responsible for triggering it.

Chemical Allergy: Certain individuals are allergic to environmental toxins such as hydrocarbons like petroleum, petroleum products, perfumes and jellies. Exposure to pollution, automobile fumes and dust can also cause an allergy headache.

Seasonal allergy: Changes in season can also cause allergy headache. For instance many people are allergic to pollen and spring is the worst time of the year for them when they are at the greatest risk of developing an allergy. Changes in weather conditions such as transition from warmer climates to colder ones can also result in an allergy headache.

Treatment of Allergy Headache:

In order to successfully treat an allergy headache, it is essential for you to figure out the exact cause of the allergic reaction. In case it is caused by a specific food, substance or synthetic dye, you must notify your doctor. Seasonal allergies can also be prevented by medication and biofeedback.
