Actual (reported)The purpose of the study is to learn about the causes of different types of pain that can occur in people who have had an amputation. By gathering information through blood tests, photographs, a nerve test, and questionnaires, we hope to de-code how each individual's special characteristics affect the type and amount of pain they experience in their amputated limb.
