Symptoms
By Mayo Clinic staffDust mite allergy symptoms caused by inflammation of nasal passages include:
- Sneezing
- Runny nose
- Itchy, red or watery eyes
- Nasal congestion
- Itchy nose, roof of mouth or throat
- Postnasal drip
- Cough
- Facial pressure and pain
- Frequent awakening
- Swollen, blue-colored skin under your eyes
- In a child, frequent upward rubbing of the nose
If your dust mite allergy contributes to asthma, you may also experience:
- Difficulty breathing
- Chest tightness or pain
- An audible whistling or wheezing sound when exhaling
- Trouble sleeping caused by shortness of breath, coughing or wheezing
- Bouts of coughing or wheezing that are worsened by a respiratory virus such as a cold or the flu
A dust mite allergy can range from mild to severe. A mild case of dust mite allergy may cause an occasional runny nose, watery eyes and sneezing. In severe cases, the condition is ongoing, or chronic, resulting in persistent sneezing, cough, congestion, facial pressure or severe asthma attack.
When to see a doctor
Some signs and symptoms of dust mite allergy, such as a runny nose or sneezing, are similar to those of the common cold. Sometimes it's difficult to know whether you have a cold or an allergy. If symptoms persist for more than one week, call your doctor.
If your signs and symptoms are severe — such as severe pain, difficulty sleeping or wheezing — call your doctor. Seek emergency care if wheezing or shortness of breath rapidly worsens or if you are short of breath with minimal activity.
