What are the symptoms of Lyme disease?
The symptoms of Lyme disease can vary greatly, but the most common early symptoms are a rash and flu-like symptoms. The rash, known as erythema migrans, usually appears near the site of the tick bite and spreads in a ring-like pattern. Other symptoms can include fever, headache, and fatigue. If the disease is not treated, it can progress and cause symptoms in the joints, heart, and nervous system.
