Mold is a common allergen that can grow indoors or outside. If you have a mold allergy, your immune system overreacts when you inhale mold spores.
The American College of Allergy, Asthma and Immunology says possible symptoms of mold allergy include:
- Stuffy or runny nose.
- Frequent sneezing.
- Wheezing or coughing.
- Itching of the throat or ears.
- Itching and swelling of the eyes.
- Difficulty breathing.
