Does lyme disease go away?

Not if untreated.: Untreated Lyme disease can progress to have cardiac (heart) and neurologic (brain and nerves) complications. If left untreated too long some damage can be permanent. Lyme disease can be treated with common antibiotics. If you have symptoms, like a bullseye rash, joint pains, fevers, or headache, and have a reasonable chance of exposure, please see a doctor for testing and treatment.
