How it works: Patients will use a sliding scale to indicate how severe their symptoms are for the listed top 15 that Dr. Weiss provided. If the symptom that they are experiencing is not on the list, they can add it by typing it into the (+) bar and searching the database. If the symptom is marked yellow or red, a "quick tip" will be provided. If a "red flag" symptom is marked red, a message will appear, asking the patient to contact their PCP immediately. I provided a slideshow to demonstrate the features of this icon.
