Google is not the best place to start looking up your symptoms. Instead, check out Isabel, a powerful symptom checker that's based on a tool used by over 100 hospitals and doctors' offices.
The site asks you for your symptoms, then shows possible diagnoses, which can be filtered by the most common conditions or the most concerning ones. Clicking on a condition takes you to resources like Wikipedia for learning more (Wikipedia is one of the few medical sites that don't track you, and Isabel is also free of tracking cookies). Other sections of Isabel explain how to use this information and connect you to a doctor.
Isabel was created by a team of doctors, and its database is deeper and more robust than other symptom checkers:
The system has undergone a rigorous validation process and over 30 articles have appeared in prestigious medical journals. It was one of only 3 systems to receive scores of over 90% in an industry survey carried out by KLAS, a leading US rating agency for healthcare IT systems.
Although the site can't replace going to an actual doctor, it can help you be more informed. (The site was started after the founder's daughter suffered a near fatal misdiagnosis. For serious cases, like Riata Wilson's nearly missed breast cancer diagnosis, it's always a good idea to get a second or third opinion and learn as much as you can.)
