• Episodes of headache not relieved by over-the-counter medication

Symptoms of Lyme Encephalopathy. In some cases of untreated disease, the infection causes a condition called Lyme encephalopathy or neuroborreliosis. This causes the following symptoms:

• Unexplained mood changes
• Depression
• Trouble concentration and remembering
• Irritability
• Feelings of "pins and needles" or numbness in the arms or legs

Other Symptoms

Heart symptoms, such as an irregular heartbeat, may develop several weeks after infection, but this is not very common. In rare cases, Lyme disease may cause eye inflammation (conjunctivitis).
