Ticks are small spiderlike animals (arachnids). They bite to fasten themselves onto the skin and feed on blood. Ticks live in the fur and feathers of many birds and animals. Tick bites occur most often during early spring to late summer and in areas where there are many wild animals and birds.
Most ticks don't carry diseases, and most tick bites don't cause serious health problems. But it's important to remove a tick as soon as you find it. Removing the tick's body helps you avoid diseases that the tick may pass on during feeding. Removing the tick's head helps prevent an infection in the skin where it bit you.
In most cases, removing the tick, washing the site of the bite, and watching for signs of illness are all that's needed.
Some people may have an allergic reaction to a tick bite. This reaction may be mild, with a few annoying symptoms. In rare cases, a severe allergic reaction (anaphylaxis) may occur.
Many of the diseases ticks carry cause flu-like symptoms, such as fever, headache, nausea, vomiting, and muscle aches. Symptoms may start from 1 day to 3 weeks after the tick bite. Sometimes a rash or sore appears along with the flu-like symptoms. Ticks are found worldwide. They can carry many diseases, including common ones such as:
- Lyme disease.
- Rocky Mountain spotted fever.
- Relapsing fever.
- Colorado tick fever.
Tick paralysis is a rare problem that may occur after a tick bite. It may cause tingling and numbness in hands or feet, double vision, and trouble swallowing. In some parts of the world, tick bites may cause other tick-borne diseases, such as South African tick-bite fever.
Check Your Symptoms
The medical assessment of symptoms is based on the body parts you have.
- If you are transgender or nonbinary, choose the sex that matches the body parts (such as ovaries, testes, prostate, breasts, penis, or vagina) you now have in the area where you are having symptoms.
- If your symptoms aren’t related to those organs, you can choose the gender you identify with.
- If you have some organs of both sexes, you may need to go through this triage tool twice (once as "male" and once as "female"). This will make sure that the tool asks the right questions for you.
Many things can affect how your body responds to a symptom and what kind of care you may need. These include:
- Your age. Babies and older adults tend to get sicker quicker.
- Your overall health. If you have a condition such as diabetes, HIV, cancer, or heart disease, you may need to pay closer attention to certain symptoms and seek care sooner.
- Medicines you take. Certain medicines, such as blood thinners (anticoagulants), medicines that suppress the immune system like steroids or chemotherapy, herbal remedies, or supplements can cause symptoms or make them worse.
- Recent health events, such as surgery or injury. These kinds of events can cause symptoms afterwards or make them more serious.
- Your health habits and lifestyle, such as eating and exercise habits, smoking, alcohol or drug use, sexual history, and travel.
Try Home Treatment
You have answered all the questions. Based on your answers, you may be able to take care of this problem at home.
- Try home treatment to relieve the symptoms.
- Call your doctor if symptoms get worse or you have any concerns (for example, if symptoms are not getting better as you would expect). You may need care sooner.
Symptoms of a severe allergic reaction (anaphylaxis) may include:
- The sudden appearance of raised, red areas (hives) all over the body.
- Rapid swelling of the throat, mouth, or tongue.
- Trouble breathing.
- Passing out (losing consciousness). Or you may feel very lightheaded or suddenly feel weak, confused, or restless.
A severe reaction can be life-threatening. If you have had a bad allergic reaction to a substance before and are exposed to it again, treat any symptoms as an emergency. Even if the symptoms are mild at first, they may quickly become very severe.
Symptoms of infection may include:
- Increased pain, swelling, warmth, or redness in or around the area.
- Red streaks leading from the area.
- Pus draining from the area.
- A fever.
Usually found in dirt and soil, tetanus bacteria typically enter the body through a wound. Wounds may include a bite, a cut, a puncture, a burn, a scrape, insect bites, or any injury that may cause broken skin.
You may need a tetanus shot depending on how dirty the wound is and how long it has been since your last shot.
- For a dirty wound that has things like dirt, saliva, or feces in it, you may need a shot if:
- You haven't had a tetanus shot in the past 5 years.
- You don't know when your last shot was.
- For a clean wound, you may need a shot if:
- You have not had a tetanus shot in the past 10 years.
- You don't know when your last shot was.
Certain health conditions and medicines weaken the immune system's ability to fight off infection and illness. Some examples in adults are:
- Diseases such as diabetes, cancer, heart disease, and HIV/AIDS.
- Long-term alcohol and drug problems.
- Steroid medicines, which may be used to treat a variety of conditions.
- Chemotherapy and radiation therapy for cancer.
- Other medicines used to treat autoimmune disease.
- Medicines taken after organ transplant.
- Not having a spleen.
Tick paralysis is a rare reaction to the venom that some ticks release when they bite. Symptoms usually start 4 to 7 days after a tick attaches to your body and may include:
- Tingling, numbness, or loss of feeling or movement that starts in your hands or feet.
- Trouble swallowing or talking.
- Double vision.
- Loss of movement in your face.
Removing the tick stops the release of the venom and reverses the problem.

Most ticks don't carry diseases, and most tick bites don't cause serious health problems. The sooner ticks are removed, the less likely they are to spread disease.
Some ticks are so small that it's hard to see them. This makes it hard to tell if you have removed the tick's head. If you don't see any obvious parts of the tick's head in the bite site, assume that you have removed the entire tick. But watch for signs of a skin infection.
Here are some things you can do to care for a tick bite.
- Remove the tick.
Use fine-tipped tweezers to remove a tick. If you don't have tweezers, put on gloves or cover your hands with tissue paper, and then use your fingers. Don't handle the tick with bare hands.
After you remove the tick, wash your hands really well with soap and water.
Don't try to burn the tick off. And don't try to smother an attached tick with petroleum jelly, nail polish, gasoline, or rubbing alcohol. This may increase your risk of infection.
- Try cold, then heat.
- Use an ice pack on your bite for 15 to 20 minutes once an hour for the first 6 hours. When you aren't using ice, keep a cool, wet cloth on the bite for up to 6 hours.
- After the first 6 hours, if you don't have swelling, try putting a warm washcloth on the bite for comfort.
- Wash the area of the tick bite with a lot of warm, clean water.
- Apply a bandage, if needed.
If you need to cover the area, you can apply a thin layer of petroleum jelly, such as Vaseline, lightly to the wound. It will keep the bite from sticking to the bandage.
- Try a nonprescription medicine to relieve itching, redness, and swelling.
- An antihistamine medicine may help. Be safe with medicines. Read and follow all instructions on the label. Don't give antihistamines to your child unless you've checked with the doctor first.
- A spray of local anesthetic containing benzocaine, such as Solarcaine, may help relieve pain. If your skin reacts to the spray, stop using it.
- Calamine lotion applied to the skin may help relieve itching.
- Check your skin for more ticks, and check your clothing, gear, and pets.
Remove any ticks you find. Then put your clothing in a clothes dryer on high heat for about 4 minutes to kill any ticks that might remain.
When to call for help during self-care
Call a doctor if any of the following occur during self-care at home:
- New or worse signs of an infection, such as redness, warmth, swelling, or pus.
- Flu-like symptoms, such as a fever, muscle aches, or chills.
- Symptoms occur more often or are more severe.
