8 Strange Signs You're Having an Allergic ReactionDealing 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.
An itchy rashSlide 2 of 17
An itchy rashAn 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.

Feeling dizzy near your cell phoneIn 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.Slide 5 of 17

Lesions on the genitalsAn 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.Slide 7 of 17
