Mold-sensitive individuals may exhibit allergy symptoms, such as sneezing, runny or stuffy nose, coughing, itchy eyes, wheezing, and skin irritation. Moreover, mold can trigger asthmatic symptoms that include coughing, wheezing, shortness of breath, and chest tightness. Mold exposure can also cause irritant reactions, in which case the symptoms are similar to those of an allergic reaction: coughing, runny nose, eye irritation, and more.
