Symptoms of allergic rhinitis usually occur shortly after coming in contact with allergens. Diagnosis is usually made based on the following symptoms:
- Sneezing, this is often paroxysmal, i.e. sudden and uncontrollable
- Itchy nose, mouth, eyes, throat, skin, or any area
- Problems with smell, for example temporary anosmia (loss of smell), hyposmia (decreased sense of smell)
- Runny nose
- Sneezing
- Tearing eyes
Symptoms that may arise later include:
- Nasal congestion (stuffy nose)
- Coughing
- Clogged ears and decreased sense of smell
- Sore throat
- Dark circles under the eyes
- Puffiness under the eyes
- Fatigue and irritability
- Headache
- Memory problems and slowed thinking
