Lyme disease is an illness from getting bitten by a tick infected with a certain type of bacteria. It can cause fatigue, headache, stiff neck, fever, sore muscles and joints, and sometimes a red rash that looks like a bull's eye.
Antibiotics usually work. If you don't get treated right away, Lyme disease can cause serious problems with the joints, nervous system, and heart.
