3Signs and Symptoms of an Allergic Reaction
The symptoms of allergies can vary from person to person, which may be mild or severe. If you are exposed to a certain allergen for the first time, it is common to experience mild problems. These include itching, rash, hives, itchy or watery eyes, scratchy throat, sneezing, or nasal congestion. More serious symptoms may occur when you are exposed to the allergen regularly. These may include diarrhea, abdominal pain or cramps, vomiting, nausea, trouble breathing, swallowing problems, chest tightness or pain, anxiety, wheezing, weakness, vertigo, dizziness, unconsciousness, face flushing, heart palpitations, as well as swollen tongue, eyes, or face.
