Hypersensitivity, Intolerance, MCS

Do you have hypersensitivity to airborne mold spores, chemicals, or other types of environmental intolerances? Post about them here, including Multiple Chemical Sensitivity (MCS). (But hypersensitivity to light or sound is discussed in the "Neurological and Sensory Sensitivity" forum, and allergic reactions are discussed in either the "Immunology, Inflammation, Allergies" forum or the "Mast Cell Activation (MCAS)" forum.)
