A tick bite may leave you feeling completely normal, especially at first. Ticks are arachnids, and their saliva can contain anesthetic properties, so you may not notice when one attaches.
A small red, itchy, or swollen spot can appear after removal. Symptoms such as fever, headache, fatigue, or body aches may point to a tick-borne illness.
If you develop a spreading rash, fever, flu-like symptoms, breathing trouble, weakness, or neurologic changes after a tick bite, contact a healthcare professional promptly. The type of tick, how long it attached, where the bite occurred, and your symptoms can all affect your risk.
Hard ticks, including members of the Ixodidae family, may become engorged after feeding, which can make identification easier.
What You May Feel After a Bite
Your immediate reaction may be limited to a small skin change. An allergic reaction can cause more widespread symptoms.
Pay attention to how the area changes and whether you develop general symptoms during the following days and weeks.
No Symptoms or a Small Local Skin Reaction
Many tick bites cause no noticeable symptoms. You may find a tick attached without feeling the bite because ticks can release saliva with numbing effects.
A small area of redness, swelling, or itching near the bite can occur. Mild irritation often improves over several days, especially after you remove the tick.
A local reaction alone does not prove that you have an infection.
Itching, Pain, and Swelling at the Bite Site
You may notice itching, tenderness, warmth, or mild swelling around the bite. Tick bites typically do not hurt right away, though the spot can become sore as your skin reacts.
Avoid scratching, and wash the area with soap and water. Take a photograph or mark the edge of redness so you can tell whether it is expanding.
A dark spot in the center may indicate that a tick remains attached.
Signs of an Allergic Reaction
A more significant allergic reaction may cause widespread hives, facial or throat swelling, vomiting, dizziness, or wheezing. Call 911 immediately for anaphylaxis, shortness of breath, throat tightness, fainting, or rapidly worsening symptoms.
Fever, headache, fatigue, muscle pain, chills, swollen lymph nodes, or joint pain are more concerning for a possible tick-borne illness than for a simple local reaction. Contact a clinician if these symptoms develop, even if the bite looks minor.
Symptoms That Can Signal Tick-Borne Illness
Tick-borne diseases can resemble one another during their early stages. Fever, chills, headache, fatigue, muscle aches, and rash are common warning signs.
Symptoms involving your nerves, heart, or joints require timely medical assessment.
Lyme Disease and an Expanding Erythema Migrans Rash
Infected ticks transmit Borrelia bacteria and cause Lyme disease. An erythema migrans, or EM rash, may gradually expand over days and can look like a bull’s-eye, though many rashes do not have that appearance.
You may also develop fever, chills, headache, fatigue, muscle aches, or joint pain. Some people later experience arthritis, facial palsy, nerve pain, palpitations from Lyme carditis, dizziness, or numbness.
Contact a clinician promptly if you notice an expanding rash or an unexplained flu-like illness after outdoor exposure.
Flu-Like Illnesses and Spotted Rashes
Rocky Mountain spotted fever, anaplasmosis, babesiosis, ehrlichiosis, tularemia, Colorado tick fever, and relapsing fever can cause fever, chills, headache, fatigue, and muscle aches. Some illnesses cause a spotted or otherwise distinctive rash, while others may not.
The lone star tick can transmit ehrlichiosis and tularemia and is associated with other tick-related conditions. Because symptoms overlap, your clinician may consider your travel or residence, exposure to wooded or grassy areas, tick appearance, symptoms, and laboratory testing.
The Centers for Disease Control and Prevention’s tickborne disease guidance notes that geography and clinical findings help guide evaluation.
Nerve, Heart, and Joint Symptoms That Need Attention
Seek urgent medical care for severe headache, neck stiffness, confusion, facial weakness, paralysis, new numbness, or progressive muscle weakness. Tick paralysis can cause weakness that moves upward through the body and may improve after you remove the attached tick, though emergency assessment remains important.
Call 911 for chest pain, fainting, severe dizziness, shortness of breath, or new palpitations. Persistent joint swelling or arthritis also deserves evaluation, particularly after a possible Lyme exposure.
What to Do Now and When to Seek Care
Prompt tick removal lowers the time available for transmission of some pathogens. Your risk depends on the tick species, location, and attachment time.
Save a clear photograph of the tick if you can, and record when and where you found it.
Remove an Attached Tick Safely
Use fine-tipped tweezers for tick removal.
- Grasp the tick as close to your skin as possible.
- Pull upward with steady, even pressure.
- Clean the bite and your hands with soap and water or alcohol.
- Dispose of the tick in alcohol, a sealed container, or tape, or flush it down the toilet.
Do not twist, crush, burn, or cover the tick with petroleum jelly or other substances. If mouthparts remain in the skin, remove them with tweezers if you can do so easily.
Do not dig into your skin.
Monitor Symptoms and Contact a Clinician
Write down the bite date, location, possible exposure area, and how long the tick was attached. Contact a clinician if you develop an expanding rash, fever, chills, headache, fatigue, muscle aches, joint pain, swollen lymph nodes, or other unusual symptoms within the following weeks.
A clinician may recommend observation, testing, or antibiotics depending on your symptoms and exposure. Do not start leftover antibiotics or rely on a negative early test without medical advice.
Seek emergency care for breathing difficulty, facial or throat swelling, chest symptoms, confusion, paralysis, or rapidly worsening weakness.
Lower Your Risk on Future Outdoor Trips
Walk through the center of maintained trails when you pass through tall grass, grassy areas, or wooded areas.
Wear long sleeves and pants. Tuck your pants into your socks.
Check your clothing, gear, children, and pets after you return indoors.
Use an EPA-registered tick repellent containing DEET on exposed skin as directed.
Treat your clothing and gear with permethrin according to the product label.
Shower and perform a full-body tick check soon after outdoor activities.
Pay special attention to your scalp, waist, groin, armpits, behind your knees, and around your ears.
