Symptom Checker

What could this be?

Tell us how you feel. We show which conditions match, how strongly and why, the treatments with the best evidence, and remedies from medicine around the world with their safety warnings.

This is information to take to a health worker, not a diagnosis. Nothing you enter is saved unless you choose to.

1. Do you have any of these right now?

2. What symptoms do you have?

3. A little about you (optional, improves the match)

Your symptom diary

On this device only.

No entries yet.

Not medical advice

The list covers common and important conditions, not every disease, and it can't examine you. If you are worried, or a symptom is severe, getting worse or not going away, see a health worker. In an emergency call your local emergency number. Explore remedies from around the world on World Medicine and research progress on the Cure Tracker.
