Quick symptom checks

These checks can help you narrow down what you might be dealing with — but they are not a diagnosis. Run a Rash Detector report for a structured AI analysis, and consult a healthcare professional for diagnosis and treatment.

Tiny burrows or intense night-time itching?

Possibly scabies. Highly contagious — see a doctor for prescription treatment.

Single 'herald patch' followed by a tree-like pattern?

Likely pityriasis rosea. Usually self-resolves in weeks.

Greasy yellow scale on scalp/face?

Could be seborrheic dermatitis. Treated with antifungal/anti-inflammatory shampoos.

Painful red, hot, swollen patch spreading rapidly?

Possibly cellulitis. Seek urgent medical care.

When to see a doctor

Seek medical attention if your rash is spreading rapidly, becoming painful, accompanied by fever, draining pus, or accompanied by difficulty breathing. Rash Detector is an awareness tool, not a diagnostic device.
