DoctorLite

Click where it hurts, or pick a condition, answer a couple of quick questions, and get general self-care information plus a clear sense of whether it's worth seeing a doctor.

This is general health education, not a diagnosis or medical advice, and it doesn't know your medical history. When in doubt, or for anything urgent, contact a doctor or emergency services.

What is DoctorLite?

DoctorLite is a self-care information tool: click where it hurts on a body diagram (or pick a condition from a list), answer a couple of quick questions about severity and duration, and get back general information — common causes, general self-care measures, and a clear signal for whether the symptom is typically something to monitor at home or worth seeing a doctor about.

How it works

Choose a spot or a condition — 15 body regions on a front and back diagram, such as the neck, lower back or knee, or one of 10 common conditions.
Answer a few questions — how bad it is on a 0–10 scale, how often it happens and for how long, and whether any of the listed warning signs apply.
Read the guide — a carefully written overview for that region or condition (common causes, self-care, gentle activity, diet notes), plus a summary from MedlinePlus, the consumer health service of the U.S. National Library of Medicine (NIH), with a link to read more.

How the "see a doctor?" answer is decided

The check is deliberately cautious and works in a fixed order. Warning signs come first: tick even one — for example numbness running down an arm with neck pain, or confusion and rapid breathing with diabetes — and the answer is to get prompt care, whatever else you said. Severity comes next: a high pain score points toward a doctor. Duration and frequency come last: something that keeps coming back or has lasted for weeks is worth a professional look. Only when none of these apply does it suggest self-care, and even then with a reminder to see a doctor if things persist or get worse.

Each lookup is anonymous. There is no account and no history, and nothing about your symptoms is stored.

This tool is for general health education only. It is not a diagnosis, not a substitute for professional medical advice, and not equipped to account for your individual medical history or circumstances. If you're experiencing a medical emergency, or anything urgent, contact a doctor or emergency services directly rather than relying on this tool.

Is this a diagnosis?

No. It gives general information about what commonly causes a symptom and what people usually do about it. Only a clinician who can examine you can diagnose.

Where does the information come from?

Two places: a hand-written guide for each region and condition, phrased as general education, and live summaries from MedlinePlus, a free public-domain health resource from the NIH.

Why only 15 regions and 10 conditions?

Each one is written by hand, so the list is kept small enough to do carefully. More will be added over time.

What should I do in an emergency?

Call your local emergency number (119 in Korea, 911 in the US) instead of using this tool. In the US, the 988 Suicide & Crisis Lifeline is available for mental-health crises.
