Additional Study Information: Auriculotherapy is a type of Eastern medicine that has been used for thousands of years involving the ear. The ear has nerve connections to the whole body, and therefore using non-invasive techniques can be used to treat a wide variety of problems. This study is looking to see if auriculotherapy might be used to treat abdominal pain and find areas on the ear that can later be used for treatment. This study does not provide any treatment. We are looking for participants with chronic or functional abdominal pain OR healthy participants without medical problems or pain. For participants who complete the study, there will be financial compensation
