| Doctors typically treat Lyme disease when a patient presents with symptoms consistent with the disease, especially after a known tick bite or residing in/visiting an area endemic for Lyme. Diagnosis often involves evaluating clinical signs like the characteristic erythema migrans rash, fatigue, fever, and muscle/joint aches, alongside laboratory testing like ELISA and Western blot to detect antibodies against the Lyme bacteria, Borrelia burgdorferi. Treatment usually consists of antibiotics, such as doxycycline, amoxicillin, or cefuroxime, particularly when Lyme is suspected early. The duration of treatment depends on the stage of the illness and the severity of symptoms, with longer courses sometimes necessary for later-stage manifestations or neurological involvement. 
A doctor will treat you for Lyme disease in the following cases:- You have symptoms of Lyme disease AND a known tick bite, especially in an area where Lyme disease is common. Symptoms can include:
- Erythema migrans (EM) rash: a characteristic bullseye-shaped rash, though it may not always appear or have the bullseye appearance.
- Flu-like symptoms: fever, chills, fatigue, headache, muscle aches, and joint pain.
- You have symptoms suggestive of Lyme disease AND laboratory tests confirm the infection. This typically involves a two-tiered testing approach:
- ELISA (Enzyme-Linked Immunosorbent Assay): This is the first test done. If it's negative and you've had symptoms for less than 30 days, further testing isn't usually needed. If it's positive or indeterminate, a second test is performed.
- Western blot (or Immunoblot): This test confirms the presence of Lyme disease antibodies. Both IgM and IgG antibodies are tested. The interpretation depends on the timing of symptoms and the specific bands that are positive.
- You have been diagnosed with Lyme disease based on CDC criteria. The CDC recommends a two-tiered blood test approach (ELISA followed by Western blot) for diagnosing Lyme disease. A positive two-tiered test with a history of possible tick exposure and symptoms supportive of Lyme disease warrants treatment.
- You have late-stage Lyme disease manifestations. Even if the initial infection wasn't diagnosed or treated promptly, doctors will often treat Lyme disease if you develop later complications, such as:
- Lyme arthritis (joint inflammation, often in the knees)
- Neurological problems (e.g., facial palsy, meningitis, nerve pain, cognitive problems)
- Cardiac problems (e.g., Lyme carditis, which can affect heart rhythm)
Important Considerations:- Early diagnosis and treatment are crucial. The earlier Lyme disease is treated, the more effective antibiotics are.
- Not everyone with a tick bite gets Lyme disease. The risk depends on the type of tick, how long it was attached, and whether the tick was infected.
- "Chronic Lyme Disease" is controversial. While some people experience persistent symptoms after treatment for Lyme disease, the existence of a chronic, persistent Lyme infection is not widely accepted by the medical community. Treatment for persistent symptoms is complex and should be managed by a physician experienced in Lyme disease.
