Lyme Disease Symptoms: What to Know After a Tick Bite

Spending time outdoors is one of the best parts of warmer weather—but it can also mean greater exposure to ticks. Whether you're hiking, camping, walking your dog, playing in the backyard, or simply enjoying a local park, tick awareness is an important part of your outdoor routine.

Ticks can carry several pathogens, including the bacteria that cause Lyme disease, the most commonly reported vector-borne disease in the United States.

Understanding the early signs of Lyme disease—and knowing what to look for after a tick bite—can help you recognize when it may be time to contact a healthcare professional.

What Is Lyme Disease?

Lyme disease is a bacterial infection transmitted through the bite of an infected tick.

According to the CDC, ticks generally need to be attached for more than 24 hours before they can transmit the bacteria that cause Lyme disease. This is one reason regular tick checks and prompt tick removal are important after spending time outdoors.

What Are the Early Symptoms of Lyme Disease?

Early signs and symptoms can develop within 3 to 30 days after a tick bite.

One of the best-known signs is erythema migrans (EM), an expanding red rash that develops around the site of the tick bite. The rash may gradually expand and sometimes develops central clearing, creating the familiar “bull's-eye” appearance.

However, not every Lyme disease rash looks like a bull's-eye, and other symptoms may occur.

Early symptoms can include:

• Fever
• Chills
• Headache
• Fatigue
• Muscle and joint aches
• Swollen lymph nodes
• An expanding rash

Because some of these symptoms can resemble other common illnesses, it is important to pay attention to recent tick exposure and discuss concerns with a healthcare professional.

What Can Happen If Lyme Disease Is Left Untreated?

Without treatment, Lyme disease can spread to other parts of the body and cause additional symptoms days, weeks, or even months after the initial infection.

Later signs can include:

• Additional rashes
• Facial palsy
• Severe headaches or neck stiffness
• Arthritis with joint pain and swelling, particularly in larger joints such as the knees
• Nerve pain, numbness, or tingling
• Heart-related symptoms in some cases

Symptoms and their severity can vary from person to person, which is why professional medical evaluation is important when Lyme disease is suspected.

Tick Awareness Should Be Part of Every Outdoor Routine

You don't need to avoid the outdoors—you just need to be more tick-aware.

When spending time in areas where ticks may be present:

• Walk near the center of trails and avoid brushing against tall grass and dense vegetation when possible
• Wear long sleeves and long pants when appropriate
• Choose light-colored clothing, which can make crawling ticks easier to spot
• Check yourself, your children, and your pets for ticks after outdoor activities
• Remove attached ticks promptly
• Follow appropriate tick-bite reduction measures for your activity and environment

Tick exposure isn't limited to a long hike in the woods. Backyards, parks, campsites, and other grassy or wooded environments can also provide suitable tick habitat.

Enjoy the Outdoors—With Tick Awareness in Mind

Ticks may be small, but knowing where they live, checking for them after outdoor activities, and recognizing the possible signs of Lyme disease can make tick awareness a simple part of your family's routine.

If you find an attached tick or develop symptoms that could be associated with Lyme disease, contact a healthcare professional for appropriate medical advice.
