Lyme disease is a controversial illness caused by tick-borne bacteria. Researching Lyme disease presents challenges due to conflicts between patients and doctors over diagnosis and treatment. Using social media to survey Lyme patients has advantages like reaching geographically dispersed patients easily, but also disadvantages like patients self-selecting and technology limitations. The politics surrounding Lyme disease can influence the research process by making patients reluctant to participate or making it difficult to influence policy. Combining research methods and addressing ethical issues are important when studying such a complex illness.
