My son was diagnosed with having a high allergy sensitivity to Stemphylium botryosum. What are the symptoms of this allergy? At this one house we go to a lot, he always breaks out with hive like rashes around his eyes and his whole face gets swollen and red. He doesn’t have trouble breathing. The floors were flooded but the people who own the house, never took out the carpets. Could this be a mold allergy? He only does this at this house only.
