The Symptoms of Allergy

When someone suffers from allergy, their hypersensitive immune system is attacked by allergens – foreign yet harmless substances. There are many symptoms of allergies, such as sneezing, itchy and watery eyes, coughing, itchy and runny nose, rashes and hives. Some people will feel weak and tired. Allergies can be seasonal and perennial. Seasonal allergy occurs mostly in the spring through autumn, although it can happen at any time during the year. Meanwhile, perennial allergy occurs all year around. For instance, one can suffer from food allergy after consuming nuts or dairy products. If the symptoms continue, sufferers should go to allergy clinic to get allergy shots to control the symptoms. More info: allergy clinic San Antonio
