If you are allergic to an airborne allergen like pollen, dust, animal dander or mold, you may experience a stuffy nose, also known as nasal congestion. As your body reacts to the allergens, the lining of your nose can begin to swell, restricting airflow in your nasal passage.

Itchy, Watery Eyes

There are a number of things that can cause a cough, and allergies is one of them. Coughing is a common symptom of hay fever, and can also be triggered by allergic reactions to pollen, dust, animal dander and mold.

Ear Ache

Airborne allergens like pollen, dust, animal dander and mold, that effect the nose and sinuses can lead to inflammation in the ear. This type of inflammation may cause a build-up of fluid that can promote infection and decrease hearing. Ears feeling full or having popping sensations are also conditions that can be caused by allergies.

Eczema (Atopic Dermatitis)

Eczema is an itchy, red rash that can appear anywhere on the skin, but is commonly found on the parts of the body that bend- elbows, knees, neck, wrists and ankles. The first signs of eczema on a person are usually apparent when they are a baby or young child. How it actually looks can vary from person to person.

Digestive Problems

Feeling sick to your stomach after eating certain foods, may be due to a food allergy. Some food allergies can cause diarrhea, gas, abdominal cramping or pain and may be accompanied by other symptoms like hives, rash or swelling. There are many conditions that can lead to these types of digestive symptoms, so be sure to see a doctor to determine the cause of any digestive issues.

Frequent Sneezing

Everyone sneezes now and then, but frequent sneezing can be caused by an abundance of allergens in the air. There are many airborne substances that can trigger frequent sneezing. Pollen is the most common cause of frequent sneezing for people with allergies, but it can also be caused by dust and animal dander.

Hives

Hives are swollen, red bumps on the skin that may itch, burn or sting. They may be caused by food allergies or by your skin coming into contact with something you are allergic to. Hives can appear anywhere on your body, including your face, throat, tongue or ears.

An itchy throat may be caused by food allergies or an allergic reaction to dust, pollen, mold, and animal dander. Discomfort from an itchy throat can range from mild to severe.

Rash

Swollen Eyelids

Swelling is a more severe type of allergic reaction. Food allergies are the most common cause of allergy related swelling, but animal dander, insect stings and certain medicines can cause it too. When the swelling occurs in the throat or lungs it becomes life-threatening as it can block the airway and cause suffocation. This type of serious condition is known as anaphylaxis. Anyone experiencing this type of allergic reaction should seek medical help immediately.
