Key takeaways
Rashes can vary
A Lyme-related erythema migrans rash may expand over time and can look different on different skin tones. Online pictures cannot provide a diagnosis.
When to get help
Contact the appropriate health service if you develop a spreading rash or feel unwell after possible tick exposure. Use guidance for the country where you are receiving care.
