Rocky Mountain spotted fever from a tick bite is rare, with about 2, cases per year in the United States. It causes a fever, a headache, muscle aches, and a skin rash. The rash of pinpoint red spots begins on the ankles and wrists after a few days of fever, but later the rash spreads to the rest of the body; in some people, a rash never develops.
Although this infection can be severe — and even fatal — it is preventable and can be successfully treated with prompt medical care, according to the CDC. Another type of tick to avoid is the lone star tick. It can transmit several viruses, the CDC notes. Symptoms of flea bites may begin within hours after you're bitten, and the bites tend to appear in groups of three or four. You may notice itching, hives, and swelling around an injury or sore, or a rash of small, red bumps that may or may not bleed.
Flea bites are most common on your ankles and legs, but may also appear in your armpits, around your waist, and in the bends of your knees and elbows. A flea-bite rash turns white when you press on it and tends to get larger or spread over time. Scratching the rash can lead to a skin infection, according to the NIH National Library of Medicine , and may need medical attention.
In extremely rare cases, fleas are infected with the bacteria that causes plague. The disease can spread from wild rodents to pets and people. Over the past 10 years, as few as 1 and as many as 17 cases of plague were reported in the United States, according to the CDC , most in the rural West. Symptoms of plague include swollen lymph nodes, headache, fever, and chills that appear from one to six days after the bite.
Beestings cause a sharp pain that may continue for a few minutes, then fade to a dull, aching feeling. The area may still feel sore to the touch a few days later.
A red skin bump with white around it may appear around the site of the sting, and the area may itch and feel hot to the touch. If you've been stung by a bee before, your body may also have an immune response to the venom in the sting, resulting in swelling where the sting occurred or in an entire area of your body, including your throat and lungs.
If you have this type of allergic response, called anaphylaxis , it is a medical emergency that needs treatment immediately. Symptoms of a severe allergy to a beesting include hives, swelling, trouble breathing, dizziness, cramps, nausea, diarrhea, and even cardiac arrest.
Lice bites are tiny red spots on the shoulders, neck, and scalp from small parasitic insects that can live on your clothes or in your bedding. Some people may develop a larger, uncomfortable skin rash from lice bites.
Continual scratching of the itchy spots could lead to an infection, marked by symptoms including swollen lymph nodes and tender, red skin. An infected lice bite may also ooze and crust over; it will need to be treated by a doctor, but lice are not known to carry other diseases. Ant bites and stings are typically painful and cause red skin bumps. Some types of ants, like fire ants, are venomous, and their bites can cause a severe allergic reaction. Fire ants bite first to hold on and then sting, giving a sharp pain and a burning sensation.
If you're bitten by fire ants , you may see white, fluid-filled pustules or blisters pictured a day or two after the sting.
These last three to eight days and may cause scars. The bumps may also be itchy and red, and you may have swelling around the site. It's important not to scratch or break open the blisters because they can become infected, notes the American College of Allergy, Asthma, and Immunology.
Carpenter ant bites are also painful because they spray formic acid into the bite, which causes a burning feeling. Mites do not usually spread disease, but their bites can irritate the skin and cause intense itching. Itch mites usually feed on insects but will bite other animals, including people.
The bites usually go unnoticed until itchy, red marks develop that may look like a skin rash. Unfortunately, there are no MedExpress centers in this area.

Chiggers Chiggers come from the larvae of a type of mite and feed on vertebrates such as humans. Wasps The vast majority of people who are stung by a wasp will only experience minor symptoms such as redness, swelling, itching, and of course, the insane stinging sensation during and after the wasp sting.
Do not swat the spider against your skin. Poisonous spiders are rare in Minnesota. Symptoms of a poisonous spider bite develop within 30 minutes to eight hours and include:.
Ticks remain attached to the skin and attempt to crawl underneath. Ticks are small — even as small as a poppy seed — so careful detection is key to removing them and preventing complications. You can photograph the tick before removing it, or place it in a small container and freeze it after removal.
Some ticks are known to carry disease, but not every tick bite requires a trip to the doctor. Monteiro explains:. Some studies indicate it could be less than 24 hours, which is why doctors recommend checking your skin for ticks every day.
Ticks tend to be found in areas with tall grass, bushes, and lots of trees and bite only when you brush up against the plants they're climbing. To prevent tick bites:. News and Stories. How to care for a typical sting Remove the stinger, if there is one, by gently scraping it out with something like the edge of a credit card. Don't use tweezers, because that can push more venom into you.
Use a cold pack or cool cloth to reduce swelling and pain. Medications to consider: an antihistamine to keep the swelling isolated and a topical anti-itch cream or spray. When to see a doctor Stings can create an allergic reaction. Seek immediate medical attention if a sting causes: Substantial swelling beyond the site of the sting or swelling in the face, eyes, lips, tongue, or throat Dizziness or trouble breathing or swallowing You feel ill after being stung 10 times or more at once If a sting becomes seriously infected, contact your primary care doctor.
Avoid floral prints and bright colors; they can look like flowers that attract the insects. Wear closed-toed shoes. When eating outside, keep food covered and garbage contained.
Avoid the sweet drinks these insects like. If beverages aren't in a sealed container, look before you sip. Stay calm if you notice a bee, wasp, or yellow jacket nearby.
Aggressive movements can lead to stings, because the insect is defending itself. An insect bite with bruising will have a ring of normal coloured skin around the bite surrounded by a larger ring-shaped bruise that is radiating out from it.
The bruised area around the insect bite will be 1-inch or wider in diameter and will look like a doughnut. If you aren't sure what type of insect bit you, or if you are worried that what you see isn't actually an insect bite with a bruise but some other form of injury, you should think about visiting your doctor and having him look at it. Some bites with bruises are harmless and will disappear on their own, while other insect bites with bruising can turn into serious, life threatening bacterial infections.
If the insect bite is very painful and the bruised skin turns brown or black or the bruised area spreads, go to the emergency room right away. These are signs that you have a staph infection.
