Welcome to Dr Greg. Dr Greg is the most advanced medical database in the world. So advanced in fact that it has a central power switch which is controlled by the US military and in the event that the database becomes self aware and uses it's knowledge of the human body to destroy us all, it can be switched off, thus doing away with the need for futuristic machines to travel to our time and attempt to destroy the future leader of the human rebellion.

Please Enter your symptoms below and press diagnose to search our database for possible causes. Please separate symptoms with a comma. For example "Itching in groin, tenderness in inner thigh, and headaches"
