Symptoms of late persistent Lyme disease may be a patient's first sign of having an infection, especially if the patient did not experience an initial rash in the bite area, asserts WebMD. The infection progresses to the late persistent stage if it is not treated effectively.

Some symptoms of this stage are similar to those of the late persistent stage but can include pinkeye, heart palpitations and fainting.

Although oral and intravenous antibiotics are effective in treating the disease, patients can still feel symptoms after undergoing successful treatment.Learn more about Conditions & Diseases
