Is Lyme disease permanent, or does it go away?

Quick answer

For most people, Lyme disease is not permanent. Antibiotics clear the infection, and CDC says people treated early usually recover quickly and completely. Some have tiredness or aches for months afterward, which usually improve over time. Lasting damage to joints or nerves is uncommon and mostly seen when infection goes untreated for a long time.

Does Lyme disease go away on its own?

The early rash often fades without treatment, which can make it seem like the illness is gone. But CDC explains that untreated infection can spread to the joints, heart and nervous system over days to months, causing problems like facial palsy, arthritis and an irregular heartbeat. That is why it is important to see a provider if you have symptoms after a tick bite, even if they seem to pass. See stages of Lyme disease.

What happens after treatment

Lyme disease is a bacterial infection, and the right antibiotics clear it in most people. Early treatment usually leads to a quick, complete recovery. Later stages are still usually treatable; some, such as Lyme arthritis or nerve involvement, may need a longer course or IV medicine. Read is Lyme disease curable? and Lyme disease treatment.

A long-term study followed people 10 to 20 years after Lyme disease and compared them with people who never had it. Overall, the two groups had similar symptoms and similar results on memory and thinking tests. Long-term problems were seen mainly in people who had facial palsy, especially those who did not get antibiotics at the time (Kalish et al., 2001).

When effects can last

• Post-treatment symptoms: some people have fatigue, body aches or trouble thinking after treatment. CDC calls this post-treatment Lyme disease syndrome. The cause is unknown, and most people improve with time. See chronic Lyme disease for both the mainstream and patient-advocate views.
• Joint damage: untreated Lyme arthritis can cause permanent damage to a joint (CDC). In some people, swelling continues after the bacteria are gone; specialists think the immune system drives this. See Lyme arthritis.
• Nerve damage: CDC notes that varying degrees of permanent nerve damage can develop in people who are not treated early and go on to late-stage disease. See neurological Lyme disease.

What helps

• Get checked early if you notice an expanding rash, fever or other symptoms after a tick bite.
• Finish the full antibiotic course your provider prescribes.
• Tell your provider if symptoms continue or come back. Other conditions can cause similar symptoms and deserve a look too.
• Be cautious about long-term antibiotics; CDC says studies found them no better than placebo and linked them to serious side effects.
