7+ Unusual Allergy Symptoms We Often Mistake for Other Diseases

In Great Britain, there’s a boy called Finley Ranson who can’t eat anything except boiled hard candies. Other products cause him to bleed. To supply Finley with protein, vitamins, and other useful substances, he has to be tube fed up. This strange reaction is caused by a severe allergy. In this article, we’re going to tell you about some other weird allergy symptoms — don’t worry, they aren’t as frightening as Finley’s.

Bright Side wants you to be healthy and happy! By the way, tackling allergies before they start turns out to be more effective than dealing with them after making contact with an allergen. That’s why it’s extremely important to always listen to your doctor.

8. Stomach cramps

Sudden acute abdominal pain may indicate that a person suffers from ulcers, appendicitis, cholecystitis, kidney stones, or other dangerous diseases. If cramps and aches aren’t that severe and occur right after eating certain dishes, you might have a food intolerance or an allergy.

The symptoms of these diseases usually resemble some digestive problems: stomach ache, diarrhea, and bloating. But there are some features that indicate you’re definitely facing an allergy:

  • Rashes or itchy areas on the skin, especially around the mouth;
  • Swelling of the tongue, lips, mouth, or throat (10-15 minutes after eating or immediately after);
  • Breathing problems;

In many cases, a food allergy is caused by peanuts, eggs, milk, fish, seafood, crustaceans, soy, and wheat. If you experience abdominal pain after eating these (or any other) products, temporarily exclude them from your diet.

7. Nausea and vomiting

In adults, nausea and vomiting usually occur in the case of food poisoning or a bacterial or viral infection. These symptoms also indicate that you may suffer from irritable bowel syndrome (usually accompanied by heartburn and bloating).

In children, vomiting may be caused by high body temperature, food poisoning, a viral infection, or severe cough.

In some cases, these are allergy symptoms and they may also be accompanied by abdominal pain, shortness of breath, skin rash, and swelling.

Keep in mind that you may be allergic to not just common allergens like fish and crustaceans, but also to bananas. Even though they are considered to be hypoallergenic, they may be dangerous too. By the way, if you experience digestive problems only after drinking a glass of milk, you may have a lactose intolerance.

6. A skin rash that looks like hives

Hives is a kind of skin rash with red, raised, itchy bumps. Hives often occur as a result of an allergic reaction to medication, an insect bite, a food allergy, cold temperatures, or getting too much sun. Sometimes hives is caused by a contact allergy (for example, you may be allergic to a cream, a detergent, or so on).

Sometimes these symptoms occur in the case of hay fever or asthma and, in some cases, it’s impossible to identify what has caused the hives. Doctors note that this rash may occur even after a workout or after contact with water.

Allergic hives shouldn’t be mistaken for an ordinary rash, which can be caused by:

  • Severe stress;
  • Infections;
  • Parasites;
  • Autoimmune diseases.

In adults, chronic hives may also indicate that a person suffers from thyroid issues, hepatitis, or cancer.

In children, if a rash occurs together with high body temperature and fever, it may be caused by an infectious disease like measles, rubella, or scarlet fever.

5. Red eyes, tears

Redness, irritation, burning, and tears may be the symptoms of allergic conjunctivitis. These features can be accompanied by sneezing and a stuffy nose.

Allergic conjunctivitis:

  • usually occurs during a certain season;
  • occurs soon after contacting an allergen;
  • is rarely accompanied by eye discharge;
  • causes vision to remain normal and your eyes don’t feel tired.

These features will help you tell an allergy from viral or bacterial conjunctivitis and dry eye syndrome.

People with seasonal allergies may have dark circles under their eyes and swollen eyelids. In difficult cases, an individual may also experience a foreign body sensation and photophobia.

Keep in mind that it’s dangerous to not treat allergic conjunctivitis, especially when it comes to severe forms of this disease. Severe redness and irritation may affect your eyesight.

4. Cough

Chronic dry cough that lasts for more than 3 weeks may be a sign of asthma or an allergy. It’s usually accompanied by sneezing and a stuffy nose.

Allergic cough may be mistaken for chronic bronchitis, a smoker’s cough, suffocation, post-nasal drip (which occurs when excessive mucus is produced by the nasal mucosa), or gastroesophageal reflux (when stomach contents rise up into the esophagus).

3. Wheezing and whistling sounds in the lungs

Wheezing and whistling sounds in the lungs usually occur because of allergies or asthma. Wheezing is often accompanied by a cough and asthma and allergies often go hand-in-hand.

It’s recommended to immediately see a doctor if you’ve never experienced any wheezing and never suffered from allergies.

Here are some more reasons that could cause wheezing sounds:

  • Acute bronchitis;
  • Heart failure;
  • Croup (in babies);
  • Pneumonia;
  • Cancer;
  • Pulmonary edema;
  • Chronic obstructive pulmonary disease, and so on.

Sometimes wheezing is caused by a foreign body, this is especially common when it comes to toddlers.

2. Tongue swelling, difficulty swallowing

Tongue, lips, and mouth swelling, and itching, irritation, or burning in the mouth are also allergy signs. As a rule, people experience them after eating nuts and some raw fruits and vegetables. People who suffer from this type of allergy are also sensitive to birch pollen, ambrosia, and some other plants.

As people who are prone to tongue and throat swelling are at a risk of anaphylaxis that may lead to death, they have to constantly carry epinephrine injections with them. In this case, it’s important to consult an allergist.

By the way, eating thermally processed fruits and vegetables is usually harmless. During boiling or baking, product proteins change their structure and don’t cause allergies.

Swallowing difficulty, wheezing, and throat pain may be caused by uvulitis, an inflammation of the uvula. In addition to allergies, the inflammation may also be a sign of the following diseases:

  • The flu or a cold;
  • Mononucleosis;
  • Croup;
  • A bacterial infection (for, example, tonsillitis);
  • Sexually transmitted diseases.

Uvulitis may also be caused by smoking, dehydration, or occur as a result of an injury.

1. Other allergy symptoms

It can sometimes be complicated to find the connection between allergies and other symptoms. To tell the difference between allergies and other diseases, you have to remember that an allergic reaction typically occurs within 15-20 minutes (and in some rare cases, within a few hours). For example: a pollen allergy won’t lead to a rise in body temperature if it’s not a complication caused by another disease.

Here are some more little-known allergy symptoms:

  • Headaches;
  • Weak pulse, dizziness;
  • Fatigue;
  • Pale or grayish skin;
  • Depression;
  • Sleep issues.

Keep in mind that severe swelling, an unhealthy skin tone, breathing issues, dizziness, and wheezing after contacting an allergen are all reasons to call an ambulance. Don’t put your life and health at risk.
