Sites such as WebMD, Healthline and Mayo Clinic all have symptom checkers that people can easily use to determine whether they should see a doctor. These sites tell users what the possible causes for their symptoms might be and what treatments are available for the condition, notes Healthline.
It is important to remember that these tools cannot diagnose conditions, however, and for a proper diagnosis, the user must be treated by a doctor. On the symptom checkers, users input symptoms, such as foot pain, abdominal pain, heart palpitations, knee pain or urinary problems and then select related symptoms, notes Mayo Clinic. From here, potential health problems related to those symptoms are brought up for the user to view. Each site also contains thorough guides for most health problems.
