how long does a tick bite rash last?
This is normal after a tick bite and does not indicate Lyme disease. However, these signs and symptoms may occur within a month after you've been infected: Rash. From 3 to 30 days after an infected tick bite, an expanding red area might appear that sometimes clears in the center, forming a bullâs-eye pattern. The rash (erythema migrans) expands slowly over days and can spread to 12 inches (30 centimeters) across. It is typically not itchy or painful.
