Our aim is to guide you on what to do before a doctor’s visit and highlight the criteria for when an in-person appointment is essential. Please remember that no online resource, however reliable, can replace an actual doctor’s consultation, as self-evaluation of symptoms can often lead to underestimating or overestimating your condition. Even the most seasoned doctors are advised not to self-diagnose. Start by using the “What are your symptoms?” tab—just as a doctor would begin by asking about your symptoms. This approach is far more effective than trying to match your condition to descriptions of various illnesses.
