How Do I Know If My Rash Is Lyme Disease

Think the Lyme Disease Rash is Always a Bull’s-eye? Think Again! | Johns Hopkins Rheumatology

Most people dont realize that a rash on their skin is a symptom of Lyme disease, but it is an important indicator of the disease. This flat, erythematous rash is the result of an infection spreading within the skins tissues. This rash may last for several days, then disappear on its own without treatment. In fact, 30 percent of people who have been infected with Lyme disease do not remember the rash. However, if you have been exposed to a tick, you should see a doctor right away to get checked out for the disease. A tick can be as small as a poppy seed, and they are hard to notice unless they are attached to your body.

A rash associated with Lyme disease often feels warm to the touch. Your healthcare provider can check this by performing a test called a crossover test. This test involves placing your hands on the rash and an unaffected area and waiting a few seconds.

What Does Lyme Disease Look Like On The Skin

There are several different rashes that may be the sign of Lyme disease. While the bulls eye rash is the most common and well known, its not always the only type of rash that may occur with this disease. Other rashes can look like an oval, circular, or triangular patch of red skin.

The rash usually appears in the first few days following a tick bite. It can be small and itchy, or it can be large and painful. In 80% of cases, the rash will appear near the bite site. However, some people will not develop a rash if they have dark skin.

Erythema migrans, or ECM, is the most common cutaneous manifestation of Lyme disease. It usually develops within 30 to 45 days after a tick bite. However, in some patients, it may appear more than six months after a tick bite. It looks like a circular, bluish-red plaque and can range in size from one to a few centimeters in diameter. Its usually on the lower extremities and often occurs around the earlobe.

Can Lyme Disease Rash Itch

If you develop a Lyme disease rash, you probably won’t be scratching your skin until it’s raw. Still, Lyme disease rashes can be slightly itchy, even mildly painful, said Dr. Aucott, but they don’t itch like a case of poison ivy.

Lyme rashes often feel warm to the touch as well. Your healthcare provider may perform what’s called a “crossover test” to gauge whether the area feels warmer than the rest of your skin, said Dr. Johnson. Here’s what that involves: Let’s say the rash is behind one knee. You place one hand on the rash and your other hand in the same area of the unaffected knee, wait a few seconds, and then switch hands. If there’s a difference in temperature, you’ll notice it.

Does The Lyme Disease Rash Come And Go

The rash that comes with Lyme disease is a characteristic sign of the disease. It is red and grows slowly around the bug bite. Sometimes the rash will be as large as a plate and it can last for weeks. If you notice these symptoms, you should visit your doctor right away.

The rash will appear within a few days to weeks after being infected, but if it is left untreated, it will spread throughout your body. When this happens, the rash is called stage two and can occur up to six months after the bite. This rash is mildly itchy, but it does not itch like poison ivy.

A rash that comes with Lyme disease usually begins at the spot of the tick bite and is up to 12 inches wide. It will be red in the center, but it may fade to form a bulls-eye. The rash can also be hot and feel tender to the touch. A typical rash will appear within 30 days of the tick bite, and it will stay for three to five weeks. However, one in five people will never experience a distinctive rash. People may also experience other symptoms such as hives, redness under the eyes, and burning.

To Infect People Lyme Disease Bacteria Uses Trial And Error

“The bacteria spend an hour or two using this behavior to find their way into the blood vessels, but once there, they are in circulation in a matter of seconds,” says Peter Searson.

New research sheds light on how Lyme disease infects the body.

The findings could better inform treatment options and help prevent severe outcomes of the disease.

An estimated 476,000 Americans are infected each year with Lyme disease, which causes a wide range of symptoms that include fever, rash, and joint pain, as well as effects on the central nervous system and heart.

Though its common knowledge that Borrelia burgdorferithe bacteria that causes the diseaseenters the body through the bite of an infected deer tick, how the bacteria manages to migrate from that bite into a persons bloodstream has not been clearly understood.

Now, researchers may have found the answer.

Using a custom designed three-dimensional tissue-engineered model, they learned that B. burgdorferi uses tenacious trial-and-error movements to find and slip through tiny openings called junctions in the lining of blood vessels near the original bite site. This allows them to hitch a ride on the bloodstream throughout the body, potentially infecting other tissue and organs.

The study appears in the journal Advanced Science.

How Is Erythema Migrans Treated

Because Lyme disease is caused by bacteria, it’s treated with antibiotics. The sooner you start antibiotics, the quicker and more complete your recovery will be.

Oral antibiotics. Early-stage Lyme disease is treated with oral antibiotics. Doxycycline is usually used to treat Lyme disease in adults and children over the age of 8. Amoxicillin or cefuroxime is usually used for younger children and pregnant or breastfeeding women. Oral antibiotics are usually given for 14 to 21 days, although a 10-to-14-day course may be just as effective.

Intravenous antibiotics. If Lyme disease involves your central nervous system, you may need IV antibiotics for 14 to 28 days. This will eliminate the infection, but it may take awhile for you to completely recover from your symptoms.

Treatment Of Lyme Disease

  • Lyme disease in pregnant women and children younger than eight years is treated with oral antibiotics.
  • Oral antibiotics such as doxycycline may be given to patients older than 8 years old.
  • Severe cases of Lyme disease are treated with intravenous administration of antibiotics
  • Pain killers may be prescribed to alleviate joint pain and other body aches.

What Are The Symptoms Of Erythema Migrans

The first sign of erythema migrans is redness at the site of a tick bite. It will start to expand into a round or oval red skin lesion. The most common manifestation of erythema migrans is a uniformly round or oval rash that expands to more than 2 inches in diameter. Sometimes the inside of the lesion clears, leaving a bull’s-eye type pattern.

Because erythema migrans is an early symptom of Lyme disease, you may also have additional symptoms of Lyme disease, including:

Do Dermatologists Treat Lyme Disease

Lyme Disease (Borreliosis) – Rash, Diagnosis, and Treatment (Deer Tick Ixodes Scapularis)

There is no definitive answer to this question as it depends on the individual case. Some dermatologists may treat Lyme disease if they feel comfortable doing so, while others may refer the patient to another specialist.

There is an option for Lyme disease treatment at the Skin Care Center of Southern Illinois. It is a bacterial illness that can spread through tick bites, as well as an inflammatory disease. The Centers for Disease Control has received reports of over 150,000 cases of Lyme disease since 1982. We recommend scheduling an appointment with our clinic in Mt. Vernon as the first step. Each stage of Lyme disease presents its own set of symptoms. Red bulls eye rash is the most common form of the diseases symptoms in its early stages. To diagnose Lyme disease, a visual examination is combined with a blood test to determine whether the bacteria is present in the blood.

Can A Bullseye Rash Not Be Lyme Disease

The bullseye rash is one of the classic telltale signs of Lyme disease, but not everyone who contracts the disease will develop the characteristic rash. In fact, up to 30 percent of patients do not show the characteristic rash. Because Lyme is such an imitator of other illnesses, its not uncommon for people to have the bullseye rash without ever experiencing the other symptoms associated with the disease.

The ticks that carry Lyme disease are tiny and are difficult to detect. The bite of a tick is not painful, and it may not be noticed for weeks or months after the bite. Ticks can be found throughout the UK and many other parts of Europe and North America, but they are particularly common in areas with overgrown plants and deep vegetation. Theyre commonly found in forests and moorland areas, but they can also be found in gardens.

A woman who presented with flu-like symptoms and a bullseye rash was diagnosed with early Lyme disease. After being treated with doxycycline, the rash cleared up within a week. She later reported experiencing generalized joint pain and irritation behind her knee. Cellulitis was the primary diagnosis, but it is not the only rash that can confuse clinicians.

Phase : Early Localized Disease

A characteristic flat, red ring or bull’s-eye rash develops in 75% of those who have been bitten by a tick infected with Lyme disease. The rash appears days to weeks after the bite and spreads outward. The bull’s-eye rash is called “erythema migrans.” Some people don’t notice or remember being bitten by a tick either because the tick was too small or a rash never appeared. Someone with newly acquired Lyme disease may suffer from fatigue, headache, joint and muscle stiffness, and swollen glands. Later stages of the disease affect the heart, joints, and nervous system.

Lyme disease is a tick-borne condition that is characterized by the development of a peculiar bulls-eye-like circular rash, and other anomalies of the heart, nervous systems, skin, and joints. Lyme disease is not a contagious illness. It is caused due to infection by a spirochete bacterium which is referred to as Borrelia burgdorferi in North America, and Borrelia afzelii in Europe.

Deer ticks are primary carriers of the bacteria. The ticks transmit the pathogen into the bloodstream when feeding on human or animal blood. The circular rash characteristic of Lyme disease is medically known as erythema migrans.

In 1975, some children from Connecticut and Lyme regions were diagnosed to be affected by some form of rheumatoid arthritis. Different studies on this anomalous incidence later indicated the cause as Lyme disease, which in turn resulted from infection by the Borrelia burgdorferi bacteria.

Most cases of Lyme disease can be fully treated with antibiotics.

The symptoms of Lyme disease tend to become life-threatening in the later stages of the illness. It is therefore important for patients to seek medical treatment as early as possible, for a complete recovery.

In some cases, the Lyme disease rash doesnt look like a bulls eye at all. It can be blistered , cause a bluish swelling , be uniform in color instead of banded, be oval or triangular in shape, or just look like a large red area . You can see a picture of atypical Lyme disease on a black man here.

There are also many instances of Lyme rashes which are considered to be bulls-eye shaped, but dont have the white band inside. The message? Dont expect a Lyme rash to look like a perfect bulls eye. If you suspect Lyme, contact your doctor!

When To Call Your Doctor

Erythema migrans is a hallmark symptom of Lyme disease. If you think you might have been bitten by a tick and youve developed a circular rash, call your doctor as soon as possible. Medical attention is particularly important if you have other symptoms of early-stage Lyme disease, which are usually flu-like.

If left untreated, Lyme disease can cause:

  • joint inflammation and pain
  • short-term memory loss

If treated early, Lyme disease can almost always be cured. Call your doctor as soon as you see erythema migrans.

Cultures And Molecular Testing

The skin lesion on Case 4 was sampled using a 3-mm skin biopsy punch, and skin biopsies were inserted directly into vials of BarbourStoennerKelly II medium, and sent by courier to the Division of Medical Microbiology, Department of Pathology, University of British Columbia, Vancouver, British Columbia. Upon their arrival, the culture tubes were incubated at 34 °C, and checked weekly for spirochetal activity. In order to avoid culture contamination, polymerase chain reaction amplification was conducted in a separate filtered laboratory. PCR testing identifies the genes of Bbsl, namely OspA, 16S rRNA, and HSP60. The OspA ), OspB , OspC , P39 , flagellin , P22 , and P93 bands were profiled using sodium dodecyl sulfate-polyacrylamide gel electrophoresis. These isolates were further analyzed for plasmid profiles pulsed-field gel electrophoresis separation of macro-restriction digests and of total DNA were applied.

Lyme Disease Skin Manifestations

Common cutaneous manifestations include borrelial lymphocytoma, acrodermatitis chronic, and atrophicansian keratodermatosis. It is a late and chronic condition that is caused by acrodermatitis and chronic atrophicans . This condition can progress from an early inflammatory stage to a chronic atrophic stage, which can be complicated by neuropathy, arthralgias, and cutaneous malignancy. ACA becomes a chronic, atrophic phase if not treated. Acute Lyme borreliosis is the most common form of erythema migrans, lymphocytoma is a subacute form, and acrodermatitis is the most common form of late Lyme borreliosis.

Seek Medical Care Early To Prevent Lyme Disease From Progressing

Understanding the Persistent Symptoms in Lyme Disease | Johns Hopkins Medicine

Its easy to get bit by a tick and not know it. Most people dont feel a tick on their skin or the bite. Checking your skin for ticks after spending time outdoors can help you find a tick and remove it.

Removing a tick can prevent Lyme disease. A tick must be attached to your skin for at least 36 hours to infect you with the bacteria that cause Lyme disease.

Its not always possible to find a tick, so its important to pay close attention to your skin. If you notice any signs of Lyme disease or develop a rash, get medical care right away. Ticks can cause other serious diseases, such as Rocky Mountain spotted fever.

What Happens At Your Appointment

The GP will ask about your symptoms and consider any rash or recent tick bites you know about.

Lyme disease can be difficult to diagnose. It has similar symptoms to other conditions and there’s not always an obvious rash.

2 types of blood test are available to help confirm or rule out Lyme disease. But these tests are not always accurate in the early stages of the disease.

You may need to be retested if you still have Lyme disease symptoms after a negative result.

Lyme Disease Skin Rash

The woman was diagnosed clinically with early Lyme disease with bullous erythema migrans.

Given the season, geographic location, outdoor activity, and progression despite treatment for cellulitis and shingles, she was clinically diagnosed with early Lyme disease, the authors report.

The woman was treated for Lyme disease with a 10-day course of doxycycline and her skin rash resolved.

Laboratory tests for Lyme disease were negative a common occurrence with early Lyme disease.

The atypical appearance of skin rash might confuse physicians with many differential diagnoses, such as spider bite, herpes zoster, bullous cellulitis, necrotizing fasciitis, and so on, the authors point out.

Editors comments: I have seen rashes described in this article in my Lyme disease patients. I am concerned when a patient is diagnosed with shingles, cellulitis or necrotizing vasculitis before Lyme disease is considered as a possible cause of an atypical skin rash.

If uncertain about the root cause of the rash, I will typically treat patients with a combination of medications including an antiviral agent and an antibiotic that is effective in treating cellulitis, a spider bite and Lyme disease.
