As the web is a wealth of information, it's typically one of the first places people go to search for symptoms when they are feeling unwell.
In acknowledgement of this, Google has changed the way that it displays information when search terms related to common symptoms are plugged into its engine. At the top of the search results, Google now displays a list of medical conditions that could be tied to particular symptoms, such a headaches, the common cold and more. This information was drawn from Google's own Knowledge Graph, as well as experts from the Harvard Medical School and Mayo Clinic.
While this information is not meant to be a replacement for advice from a medical professional, Google also does suggest a few self-treatment options that may prevent the need to see a doctor.
