There are many types of allergies but the most common are triggered by seven groups of external factors. Drug allergies, food allergies, insect allergies, latex allergies, mold allergies, pet allergies, and pollen allergies.    Typically, symptoms of an allergic reaction begin to display themselves within a few minutes of exposure to the allergen. Sometimes, they appear more slowly, developing over the course of hours. An undeniable inconvenience, most allergies are fairly mild, with the exception of anaphylaxis, a rare severe reaction.    Among the most common symptoms of an allergic reaction are wheezing and chest tightness, coughing, sneezing, a blocked, runny, or itchy nose, hives, dry, red, or cracking skin, swollen tongue, eyes, face, or lips, watering eyes. Symptoms differ based on the nature of the allergy and how you interact with the allergen.   It is important to see a physician if you are displaying the above symptoms and they can determine if the symptoms are being caused by an allergy or another condition.
