My son never had an issue with a mold allergy until he went to college. When he could not shake the congestion and cold last year, and the student health center kept saying he had a virus, I took action. I spent spring break (I am a teacher in another state) taking him to a lung specialist. He tested my son for all sorts of allergies, and mold came back positive. When he was home for the summer, he was fine. He has returned to school, and yes, the mold issue has returned. He believes there could be a problem with the AC where he lives, so he filed a work order. No response. So he told me he will file them weekly. My husband offered to contact the school, but he does not want us involved.
