Allergies can cause symptoms that go well beyond the tell-tale red eyes, runny nose, sneezing and case of the sniffles.
The American College of Asthma, Allergy & Immunology says additional symptoms of allergies may include:
- Allergic shiners, characterized by dark circles under the eyes.
- A tired, droopy look to the face caused by swollen adenoids.
- A line that forms on the bridge of the nose, called a nasal crease, from frequently rubbing of an itchy nose.
- Breathing through the mouth.
