Tick bites can spread the bacteria that cause Lyme disease.

Lyme disease is an inflammatory disease that can impact the joints, heart and nervous system. Symptoms include rash, fever, headaches and joint pain. Lyme disease is caused by a species of bacteria that's most often spread to humans through tick bites.

Chronic Lyme disease is a controversial diagnosis -- not all doctors believe that it exists. Those who believe in it think that antibiotic treatment that usually cures Lyme may sometimes be ineffective, leading to an on-going infection that can cause persistent and possibly debilitating symptoms.

Some chronic fatigue syndrome doctors and researchers believe that chronic Lyme disease may play a role in causing and/or sustaining chronic fatigue syndrome. Research has thus far failed to confirm the connection.
