Spider Bite

How common are spider bites? — Spider bites are very rare. Most spiders’ fangs are not strong enough to poke through your skin. Also, spiders do not usually bite unless they are crushed between you and another object.

Most people who think a spider bit them were usually bitten by a different insect, such as a tick. Also, some skin infections can look like a spider bite.

How dangerous are spider bites? — Most spider bites are harmless. The poison that most spiders inject when they bite (called “venom”) is not toxic to people. But a few types of spiders can give painful bites. In rare cases, the bites get infected or cause other serious symptoms.

Some types of dangerous spiders live only in Australia or South America. But some are found in countries all over the world, including the United States.

What are the symptoms of a spider bite? — Symptoms include a small, red, raised bump on the skin. The bite might itch or burn.

Some bites do not start to hurt until a few hours after the bite. The pain can range from a slight prickly feeling to very bad pain.

In rare cases, spider bites can cause:

●Redness, swelling, and pus

●Flu-like symptoms such as feeling tired and sick to your stomach, throwing up, and fever


●Very bad muscle pain

●Very bad belly pain

●Dead tissue – When this happens, the center of the red bump turns a dark red, blue, or black, dries out, and forms a sore. This is called “necrosis” and can happen several days after a spider bite. The sore is usually about the size of a quarter but can grow larger. Most heal after a few weeks but some last for months.

What should I do if a spider bites me? — If you are bitten by a spider, you should:

●Wash the area that was bitten with soap and water.

●Put a cold gel pack, bag of ice, or bag of frozen vegetables on the painful area every 1 to 2 hours, for 15 minutes each time. Put a thin towel between the ice (or other cold object) and your skin.

●If you can, keep the bitten area raised up above the level of your heart.

●Try to figure out what type of spider bit you.

Should I see a doctor or a nurse? — See a doctor or nurse if you get any of the rare symptoms listed above.

How are spider bites treated? — Treatment involves cleaning the area well and taking medicines if needed. Depending on your symptoms, your doctor or nurse might recommend:

●Medicine for pain, such as ibuprofen (sample brand names: Advil, Motrin)

●Medicines to treat muscle spasms, called benzodiazepines

●A tetanus shot – Tetanus is a serious infection that causes muscle spasms and stiffness. It is caused by bacteria that can get in your body through a cut, scrape, or bite.

●Antibiotics – If there are signs of infection (such as a fever, red skin, or pus coming from the bite), a doctor will prescribe antibiotics. But most spider bites do not get infected.

People who have dead tissue because of a bite sometimes need surgery to remove the dead tissue.

People who are bitten by a widow spider and have severe pain and muscle spasms that don’t get better with other treatments sometimes get a special medicine called “antivenom.”

What can I do to reduce the chances of getting a spider bite? — To avoid a spider bite, be extra careful in places that dangerous spiders live

Bed Bugs

What are bedbugs?

Bedbugs are small bugs that do not fly. They are found all over the world. Bedbugs can live in hotels, houses, and other places where people rest and sleep. They can live in your mattress, your clothes, the walls, and other parts of your house. Most often, they bite you while you are sleeping or resting.

If you have bedbugs in your home, you might not be able to see them. They are very small and hide during the day. Bedbugs do not spread diseases in people.

What do bedbug bites look like?

Bedbug bites are small, red and swollen areas of the skin that are often:

In a row or a line

On parts of the body not usually covered by clothes, such as the face, neck, arms, and hands

Very itchy

Most people don’t feel it when they get bitten. They might notice the bites in the morning or after a day or 2. Bedbug bites can take 3 to 6 weeks to heal. They can get infected if you scratch them a lot.

Is there a test to tell if I have bedbug bites?No. There is no test. But your doctor or nurse might suspect that your bites are from bedbugs when he or she looks at your skin. Other types of bugs and some diseases can also cause red bumps on the skin that look like bedbug bites.

The only way to know for sure if you have bedbugs in your home is to catch one. Your doctor or nurse can then inspect the insect. They can tell if it is a bedbug or another type of bug.

Is there anything I can do on my own to help my bites feel better?Yes. To help your bites feel better and heal faster, you can:

Keep the skin clean and dry

Try not to scratch the bites

Use an anti-itch lotion or cream to help with the itching

Should I see a doctor or nurse?

See your doctor or nurse right away if the bites:

Get redder

Get more swollen

Start having pus come out of them

If any of these things happen, your bites might be infected. Your doctor or nurse might prescribe medicine for the infection. When you first find out you have bedbugs in your home, you might feel very worried or upset. If you feel this way, talk to your doctor about what you can do.

What should I do about the bedbugs in my home?

You will need to get rid of the bedbugs in your home so you do not get any more bites. To start, you can:

Vacuum your home

Wash your clothes and bedding, and dry them in a dryer that is on the hottest setting

Clean up your home

Then, you or your landlord should call a pest control service. The workers might use a chemical in your home to get rid of the bedbugs. You should not try to use any chemicals yourself. Another way that pest control services can get rid of bedbugs is a special type of heat treatment. This raises the temperature in your home, which kills the bedbugs. If you want to get rid of some of your clothes or things, do not give them to other people. The bedbugs could still be in them. You do not want to spread bedbugs to other people.

Can bedbug bites be prevented?The only way to prevent bites is by getting rid of the bedbugs. Also, do not sleep or stay over in a place that you know has bedbugs.

Brown Recluse Spider Bites

In this patient education video we discuss the diagnosis, treatment, and follow up of spider bites caused by the brown recluse spider. Even though we see many patients coming into the ER because they were bit by a spider, most of the time is really infection by MRSA causing boils and abscesses. screen-shot-2016-07-20-at-9-31-52-am Dr. Carlo Oller Board Certified Emergency Physician Please visit my website, www.DrER.tv make sure you subscribe, comment, and share!
