Frequently Asked Questions

Common questions about our symptom checker and how to use it safely.

A symptom checker is an interactive health tool that helps you organize and understand your symptoms. It asks about what you're experiencing, where the symptom is located, how severe it is, and how long it has lasted. Based on your answers, it provides general educational guidance about possible causes, warning signs to watch for, and whether you might want to seek professional medical care. It is not a diagnostic tool and should never replace a consultation with a qualified healthcare provider.

No. DrSymptoms does not diagnose medical conditions. It provides educational information to help you better understand your symptoms and prepare for a conversation with your healthcare provider. Only a qualified clinician can provide a medical diagnosis after a proper examination.

Seek immediate medical attention if you experience difficulty breathing, chest pain or pressure, sudden confusion, severe or uncontrollable bleeding, loss of consciousness, sudden weakness or numbness on one side of the body, or any symptom that feels life-threatening. When in doubt, call your local emergency number (911 in the US) or go to your nearest emergency department.

Yes. Your symptom data is processed entirely within your web browser and is not sent to or stored on our servers. We do not collect, store, or share any personal health information you enter into the symptom checker.

Certain symptoms warrant prompt medical evaluation. These include sudden severe headache, chest pain or tightness, difficulty breathing, unexplained weight loss, persistent fever, sudden vision changes, signs of stroke (face drooping, arm weakness, speech difficulty), severe abdominal pain, and any rapidly worsening symptom. If you experience any of these, contact a healthcare professional right away.

This symptom checker is designed for adults and may not be appropriate for evaluating symptoms in infants, children, or adolescents. Pediatric symptoms can present differently than adult symptoms, and children should always be evaluated by a qualified pediatric healthcare provider. If your child is experiencing concerning symptoms, contact their pediatrician or seek urgent care.

While the symptom checker can provide general health information, it is not specifically designed for pregnancy-related symptoms. Pregnancy can change how symptoms present and what they may indicate. Always consult your obstetrician, midwife, or healthcare provider for any symptoms during pregnancy. If you experience severe abdominal pain, heavy bleeding, severe headache, or other concerning symptoms during pregnancy, seek immediate medical care.

Online symptom checkers, including DrSymptoms, are educational tools with inherent limitations. Research shows that symptom checkers can help with general health literacy and triage guidance, but they are not a replacement for professional clinical evaluation. Their accuracy varies based on symptom complexity, and they cannot account for your complete medical history, physical examination findings, or diagnostic test results. Always use them as a starting point for understanding your health, not as a final answer.
