Mold allergy triggers asthma
and nasal symptoms in susceptible persons.
Of course, many inhaled allergens trigger such symptoms. Suspect mold if there's a moisture problem in your home. Look for wet carpeting, water stains on ceilings & walls, condensation on or around windows, discoloration of shower curtain, tiles & grout & leaks around sinks & hot water heaters. See a board-certified allergist.
