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.

Patches with thick silvery scale?

Often psoriasis. Most common on elbows, knees, scalp, and lower back.

Red flushed face with visible blood vessels?

Could be rosacea. Avoid known triggers (sun, alcohol, spicy food) and consult a dermatologist.

Itchy creases of the elbows or knees?

Classic eczema pattern. Moisturize daily and avoid known triggers.

Sudden welts after eating something new?

Likely hives. Severe reactions (face/lip swelling, breathing trouble) need emergency 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.
