What are the symptoms of allergies?
According to the Asthma and Allergy Foundation of America, allergies are an overreaction of the immune system to allergens, or foreign protein substances that produce symptoms by being eaten, breathed, injected or touched. Symptoms include coughing, sneezing, itchy eyes, runny nose and scratchy throat. In severe cases it can also result in rashes, hives, lower blood pressure, difficulty breathing, asthma attacks, and even death.
