Make sure the affected area is clearly visible in good lighting, and have photos showing how the rash has changed, if available. Be ready to discuss when it began, your symptoms, possible exposures, new medications or products, and treatments you've already tried.

Call 911 if you develop a rash along with signs of a severe allergic reaction, such as breathing problems, sudden dizziness, or feeling faint.

Seek prompt in-person care if a rash spreads quickly, covers much of your body, is very painful, causes blisters or peeling skin, or occurs with a fever. Rashes affecting the eyes, mouth, or genitals should also be evaluated promptly.

Your provider may also recommend testing, a dermatology consultation, or other in-person follow-up if the cause is unclear or the rash isn't improving.
