Start with your primary care doctor, not a specialist
If you think you have Lyme disease, call your primary care doctor first. They can examine you, order the blood tests that detect Lyme antibodies, and start treatment if the clinical picture fits. You do not need a referral to a specialist to begin — in fact, most cases are diagnosed and treated in primary care.
Tell your doctor when the tick bite happened (if you saw one), where you were when it occurred, and what symptoms you have now. Lyme disease has a recognizable early rash called erythema migrans — a red circle that expands outward, sometimes with a clear center — but not everyone gets one. Fever, joint pain, fatigue, and headache can appear with or without the rash.
Your doctor will order a two-step blood test if Lyme is suspected. The first test screens for Lyme antibodies; if positive, a second test called a Western blot confirms it. Results take several days to a week. While you wait, your doctor may start antibiotics if your symptoms and exposure history are convincing enough — you do not have to wait for test results.
Key Takeaways
- Call your primary care doctor if you have symptoms after a tick bite or time in a wooded area; they can order tests and start treatment without a specialist referral.
- The two-step blood test (screening followed by Western blot) is the standard way to confirm Lyme disease, and results take several days to a week.
- Early treatment with oral antibiotics (usually doxycycline, amoxicillin, or cefuroxime) is most effective and can prevent later complications.
- If your primary care doctor is unsure or your symptoms persist after treatment, ask for a referral to an infectious disease specialist.
- Keep records of when symptoms started, what you were doing when exposed, and any rash photos — this information helps your doctor make the diagnosis.
What happens during the doctor visit
Bring a timeline: when you were in a tick-prone area, when you first noticed symptoms, and what those symptoms are now. If you have a photo of a rash, bring it. Your doctor will ask about joint pain, neurological symptoms (tingling, facial drooping, memory problems), and heart symptoms (irregular heartbeat, chest pain), because Lyme can affect multiple body systems if untreated.
The physical exam includes checking for the characteristic rash and testing for signs of joint inflammation or nerve involvement. Your doctor may also ask about other tick-borne illnesses you could have caught at the same time — co-infections are common in areas where Lyme is endemic.
If your doctor suspects Lyme, they will order the two-step blood test. Some doctors also order tests for co-infections like babesiosis or anaplasmosis if you were in a high-risk region. Insurance usually covers these tests when ordered by your doctor with clinical suspicion of Lyme disease.
Understanding the blood tests
The first test, called an ELISA or enzyme-linked immunosorbent assay, screens for antibodies to Borrelia burgdorferi, the bacterium that causes Lyme disease. A positive ELISA does not confirm Lyme — it means antibodies were found and the second test is needed.
The second test, the Western blot, is more specific. It identifies which proteins your immune system is reacting to. A positive Western blot after a positive ELISA confirms Lyme disease. If the ELISA is negative, the Western blot is usually not done, because the chance of a false positive is high.
Timing matters: antibodies take one to two weeks to appear after infection. If you are tested very early (within the first week of symptoms), you may get a false negative. Your doctor may recommend retesting in one to two weeks if suspicion is high but the first test is negative.
Early treatment and what to expect
Early Lyme disease is treated with oral antibiotics. Doxycycline is the first choice for adults and children over 8 years old; amoxicillin or cefuroxime are used for younger children and pregnant people. The course is usually 14 to 21 days depending on which antibiotic and which stage of disease.
You should start feeling better within a few days to a week. Fever and fatigue usually improve first; joint pain may take longer. Some people have lingering fatigue or joint aches for weeks after treatment ends, even though the infection is cleared. This is not the same as treatment failure — it is post-treatment Lyme disease syndrome, and it typically resolves on its own over months.
If you have neurological symptoms (meningitis, facial nerve paralysis) or heart involvement, your doctor may recommend intravenous antibiotics in a hospital or infusion center. These are less common but more serious, and they require specialist involvement.
When to ask for a specialist referral
Ask your primary care doctor for a referral to an infectious disease specialist if: your symptoms do not improve after a full course of antibiotics, you develop new symptoms weeks after treatment, you have neurological or cardiac symptoms, or your doctor is uncertain about the diagnosis.
An infectious disease specialist can order additional tests, review your blood work in detail, and consider whether your symptoms are from Lyme disease or from something else that mimics it — fibromyalgia, chronic fatigue syndrome, and autoimmune conditions can look similar. They can also manage more complex cases or co-infections.
Specialist appointments typically take two to four weeks to schedule. If your symptoms are severe or worsening, tell your primary care doctor so they can prioritize the referral or direct you to urgent care in the meantime.
What to do if you cannot see a doctor right away
If your primary care doctor has a long wait, call and ask if you can be seen sooner or if an urgent care clinic can evaluate you. Many urgent care centers can order Lyme tests and start antibiotics. Describe your symptoms clearly — fever, rash, joint pain, or neurological changes — so the clinic knows this is time-sensitive.
If you are in a rural area or do not have a primary care doctor, call your local health department. They can tell you where to go for tick-borne illness evaluation and may have information about Lyme disease in your region.
Do not wait weeks to be seen if you have a clear rash or high fever. Early treatment prevents complications. If you cannot reach your regular doctor, urgent care or a walk-in clinic can start you on antibiotics the same day.
Keeping records and next steps
Save copies of your test results, the antibiotic prescription, and the dates you took the medication. If symptoms persist or return, you will need this record to show your doctor what has already been done. Take photos of any rash while it is visible — these are useful if you need to see a specialist later.
After treatment, most people recover fully. Some have lingering symptoms that fade over weeks to months. If you are still symptomatic three months after treatment, contact your doctor to discuss whether further testing or specialist evaluation is needed.
Report the tick bite to your local health department if you know where it happened. This helps track Lyme disease patterns in your area and can inform public health decisions about tick prevention.
Frequently Asked Questions
Can I treat Lyme disease without antibiotics?
No. Lyme disease is caused by a bacterium that requires antibiotics to clear. Without treatment, the infection can spread to joints, the nervous system, and the heart. Early antibiotic treatment prevents these complications and is the standard of care.
What if I do not remember a tick bite?
Many people do not see or feel the tick. If you have symptoms consistent with Lyme disease and were in a wooded or grassy area in the past month, tell your doctor. They can still order tests based on your symptoms and exposure history alone.
How long does it take to feel better after starting antibiotics?
Most people improve within a few days to a week. Fever and fatigue usually go first. Joint pain may take longer. If you feel no better after one week, contact your doctor — it may mean the diagnosis is wrong or you need a different antibiotic.
Can Lyme disease come back after treatment?
True reinfection is possible if you are bitten by another infected tick, but the original infection does not return if treated with antibiotics. Some people have lingering symptoms after treatment that feel like the disease is back; this is post-treatment syndrome, not active infection, and it usually resolves over time.
Do I need to see an infectious disease doctor or can my regular doctor handle it?
Your regular doctor can diagnose and treat uncomplicated early Lyme disease. See a specialist if your symptoms are severe, involve the nervous system or heart, do not improve after treatment, or if your doctor is unsure about the diagnosis.
