Intro 8 Strange Signs You’re Having an Allergic Reaction

Dealing with allergies is tough. More than 5 million Americans have some type of allergy, according to the American College of Allergy, Asthma and Immunology.

Most of the time, the body responds to outdoor and indoor allergens with mild reactions, such as a runny nose or sneezing. Sometimes, the reaction is more severe, such as stomach cramps, dizziness or difficulty breathing.

But some allergy sufferers react in more unusual ways.

Take a look at 8 strange signs that you’re having an allergic reaction.

8 An itchy rash

An 11-year-old boy developed an itchy rash on his abdomen and under his wristwatch a week after he was fitted for his braces, according to a 2004 case report published in the journal Dermatitis.

It turned out, the boy was allergic to the nickel in the braces. The silver-colored metal is often mixed with other metals and is found in coins, jewelry eyeglass frames, key and home fixtures.

Nickel is also the most common metal that people have allergic reactions to, and it’s known to cause a red, itchy, bumpy rash.

7 Feeling dizzy near your cell phone

In a world filled with cell phones, mobile devices, and flat screen TVs, exposure to an electromagnetic field, or EMF, is pretty common — at least, at a low frequency.

But there have been several cases of people who claim to be sensitive to EMF. Often called “electromagnetic hypersensitivity,” or EHS, people experience dizziness, nausea, headache and sleeping problems if they’re in close contact to an electronic device.

One case, reported in 2011 in the International Journal of Neuroscience, researchers said that a female doctor who claimed to have EMF sensitivity did in fact develop pain, headache and muscle twitching when she was exposed to an EMF in a double-blind experiment.

But others have doubted such cases, and research hasn’t shown how exposure to EMF might trigger an allergic response.

6 Lesions on the genitals

An unusual skin lesion isn’t necessarily the sign of a sexually transmitted disease.

According to a study published in January in the Journal of Sexual Medicine, a 42-year-old man had an allergic reaction after having sex with a partner who had used a medicated vaginal cream.

The man had a sensitivity to co-trimoxazole, an antibiotic used to treat bacterial infections and often found in vaginal creams. He developed strange lesions on his penis after having sex with his wife.

This was the fourth case reported of an allergic reaction to vaginal cream, the researchers said.

5 Skin tumors

Some people who get permanent tattoos develop strange skin growths. In 2008, University of Maryland researchers reported a case of a 38-year-old man who developed a skin tumor one month after getting a tattoo.

In another study, published in 2010 in the Journal of Cutaneous Pathology, researchers analyzed eight people of tattoo-related skin tumors, and found that red tattoo ink was associated with most of the skin tumors.

Experts say the skin recognizes the red ink as a foreign substance, and triggers an immune response.

4 Blisters, hives and swollen skin

There are people who are allergic to the sun and experience symptoms such as blisters, hives and swelling of the skin when they’re exposed to it.

According to a 2011 study from researchers in Germany, about 10 to 20 percent of people in Europe, United States and Scandinavia suffer from a sun allergy.

The abnormal reaction to sunlight is usually due to ultraviolet rays, according to the Mayo Clinic.

3 Black spots on the skin

An itchy rash may be a common allergic reaction to poison ivy or poison oak, but there are also rare cases where people develop black spots, according to a 2008 study published in the journal Dermatitis.

Black shiny deposits form on the skin and clothing when a high amount of resin, the toxic plants’ oily secretion, is exposed to the air.

The researchers said the spots eventually peel off, and the skin heals without scarring.

2 Swollen tongue

People who suffer from hay fever might have something besides hay itself to worry about: Some fruits and vegetables contain proteins similar to those found in hay pollen. They can cause an allergic reaction such as itchiness or swelling of the mouth, face, lip, tongue and throat.

Known as oral allergy syndrome, the condition occurs when the immune system behaves as though the protein found in some fruits and vegetables and the pollen in the air are the same.

The syndrome affects up to one-third of allergy sufferers and can occur at anytime, according to the American Academy of Allergy, Asthma and Immunology.

1 A bright red butt

People exposed to certain metals, medications and plants or herbs, can develop Baboon Syndrome. That’s right, the condition means developing a bright red rash, primarily on the butt, closely resembling a baboon’s butt, according to research reports.

The red rash can appear on the anus, genitals and inner thighs, and can be itchy and painful, but the syndrome doesn’t pose any serious health risks.

Exposure to metals such as mercury, gold and nickel, can trigger a reaction, according to 2011 article in the American Journal of Clinical Dermatology. Recent studies have shown that antibiotics and antibacterials administered by mouth, intravenously or on the skin can also trigger the reaction.
