What does a Lyme disease rash look like?

Lyme disease is often recognized by a distinctive rash called erythema migrans. This rash typically appears as a red, circular patch that can expand over time. In some cases, it may look like a bull's-eye, with a red outer ring surrounding a clear area and a red center.

Characteristics of the Rash:

• Shape and Size: The rash is usually round or oval and can grow to several inches across.
• Color: It starts as a red spot and may develop a central clearing, giving it a bull's-eye appearance.
• Location: It often appears at the site of the tick bite but can show up on other parts of the body.
• Symptoms: It may be warm to the touch but is usually not painful or itchy.

This rash is an early sign of Lyme disease, appearing within 3 to 30 days after a tick bite. It's important to note that not everyone with Lyme disease develops this rash, so other symptoms like fever, chills, and body aches should also be considered.
