Addiction medicine deals with patients suffering from a wide variety of addiction problems. It aims to free people from their addictions while providing support, counseling, and mental health services. Medical professionals who work in addiction medicine can help patients work through the detoxification process as well as provide harm reduction tactics and rehabilitation services. They may also treat conditions like hepatitis and HIV, which are related to addiction issues. This type of medicine is often associated with public health.

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.
