Emergency medicine is a subspecialty that focuses on patients who need immediate and often intensive care. These physicians must be able to handle medical problems quickly to avoid potential complications with their patients. With their knowledge of emergency medicine comes knowledge about many other types of medicine, as they must be able to respond to patients who present a variety of symptoms and problems. They will also have a thorough understanding of emergency medical devices.

Pain management is a wide branch of medical study, and it can include a complete range of different therapies for those suffering from pain. Since pain can come from many parts of the body for different reasons, the solutions will differ greatly. Some doctors will prescribe pain medication to their patients, but in recent years, there has been a push to explore more medication-free pain management options, such as physical therapy, surgery, and even acupuncture and other alternative therapies.
