Some of us are just more sensitive than others. Fox says some of the symptoms of environmental illness and chemical sensitivity include inflammation of the nose, sinus pain, coughing, shortness of breath and even the change in the ability to think clearly. A person might experience shivering spells, hot flushes, blurred vision, one's hearing might become extremely sensitive to sounds, cramping, diarrhea and an irritated bladder. I remember talking to a woman at the clinic who had it though. She told me she couldn't even remember her children's names.
Some people have immediate reactions to the chemicals or toxins they are exposed to.
Others have delayed reactions. Fatigue, depression and skin irritations can also occur after exposure. The problem with diagnosing MCS is that it is difficult to detect the source of a person's illness. Fox says multiple factors contribute to its development. He says natural substances manufactured with chemicals are irritating as are most synthetics.
