The purpose of these questions is to document your symptoms before and after clinical or medical treatment. Did your symptoms get better or worse after taking certain medications (antibiotics), physical or psychological therapies, medical/surgical interventions (anesthetics, implant removal, chemotherapy), 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 clinical intervention. 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 the clinical intervention.

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 symptoms before the intervention and a  blue diagram representing your current symptoms after your the intervention.
