The purpose of these questions is to document symptoms you attribute to particular exposure events. Did your symptoms worsen after exposure to pesticide extermination/fumigation, mold, remodeling/new construction, or when you changed homes or jobs, or after medical/surgical treatment (anesthetics, antibiotics), etc.?

Two identical sets of 10 questions will be shown to you twice. The first set refers to your current symptoms, how you feel now after your exposure. When you have completed the first set of questions, the next 10 questions will be shown to you. For these questions, recall what your symptoms were like before your exposure.

Next, the program will automatically draw your responses and show them to you. The final result will be two diagrams as illustrated here—a red diagram representing your current symptoms after the exposure and a  green diagram representing your symptoms before your exposure.
