2 AnswersSeverity of an allergy is usually determined by how one's immune system reacts to the allergen, such as pollen. The chemical histamine released by certain cells in your body that cause the reactions can be mild, causing a mild symptoms or severe, leading to serious symptoms. Also, prior exposure to an allergen and the amount of pollen in the environment can determine the severity of the allergy.
1 AnswerDr. Mehmet Oz, MD , Cardiology (Cardiovascular Disease), answeredPull down your lower eyelid and look in the mirror. If you notice little bumps inside the eyelid that look like cobblestones, it's a telltale sign of allergies. Some of the most common culprits are dust, pet dander, and mold. To combat allergies, try using a HEPA filter in your home and keeping your beloved pooches and kitties out of your bedroom -- or, at least, off the bed.

1 AnswerDr. Lawrence T. Chiaramonte, MD , Allergy & Immunology, answeredIf the air is completely free of the substances an allergic patient is sensitive to, there will be no allergy symptoms. If someone is dust sensitive, for example, and moves to the top of the Swiss Alps where the air is very clean, cold, and dry, her allergic symptoms will disappear. Similarly, if a cat-sensitive asthmatic gives away his cat, his asthma often improves dramatically.
1 AnswerDr. Paul M. Ehrlich, MD , Allergy & Immunology, answeredImmunoglobulin E (IgE) is the main antibody seen in allergic disease. Its primary role is thought to be defending against parasites. Levels are often checked to determine the degree of allergy or atopy a patient has. Elevated levels often correlate with severe eczema.

If you have a diagnosis determining what your allergy is, and you can easily control your symptoms with medication or by avoiding the allergen, you may not need to talk to your physician further. However, if your symptoms increase or are not being fully treated by your medication, talk to your doctor about your options. In addition, if your condition changes-you are pregnant or plan to become pregnant, for example-speak to your physician as certain allergy medications should be avoided during pregnancy. If you are unsure about anything, always talk to your doctor.
4 AnswersStacy Wiegman, PharmD , Pharmacy, answeredIt can be hard sometimes to figure out if you have allergies or a cold. Here are some main differences between the two:
- The mucus produced by a cold gets thick and may turn yellow or green. Mucus is typically clear with allergies.
- A sore throat is more common with a cold than with allergies.
- Colds often bring on a low fever (especially in children). Allergies never cause fever.
- Both colds and allergies can cause coughing and sneezing, but coughing is more common with colds, and sneezing is more common with allergies.
- A cold should clear up within a week to 10 days. An allergy can drag on for as long as you're exposed to what's causing it.
- A cold is most common in winter, while allergies can crop up any time of year.
- Itchy eyes are a classic sign of allergies but don’t occur with colds.
- Both colds and allergies can cause fatigue, but aches and pains usually indicate a cold or even the flu.
2 AnswersSymptoms of seasonal allergies include runny nose, watery eyes, sneezing, and general malaise. If you experience these symptoms in spring or fall and they are relieved by an over-the-counter allergy medicine such as Claritin or Zyrtec, you can safely diagnose yourself with seasonal allergies.
2 AnswersThere are several causes of scratchy throat, such as postnasal drainage, allergies, the common cold, and acid reflux. Treating the cause will generally help the symptom of scratchy throat. Some of the home remedies that you could employ are gurgling with salt water, drinking honey with tea, using a humidifier, and avoiding triggers if you know you have allergies.
1 AnswerDr. Clifford W. Bassett, MD , Allergy & Immunology, answered
Facial markers that can indicate that you have allergies include allergic shiners (puffiness under eyelids), lines in the lower eyelid and a distinctive crease in your nose from rubbing. Watch allergist Clifford Bassett, MD, explain these symptoms.
1 AnswerDr. Paul M. Ehrlich, MD , Allergy & Immunology, answeredYou only become allergic to things after you have already been exposed to them. An allergic response cannot take place upon first exposure to an allergen; sometimes that fact provides some very poignant glimpses into people's lives. For example, we once had a teenage patient from an observant Jewish family. His general practitioner had ordered a standard battery of radioallergosorbent test (RAST) tests and when son and father arrived to hear the results, I was chagrined to find a reaction to shrimp and lobster. These delicacies are not allowed under dietary laws observed by both devout Jews and Muslims, who are restricted to eating only kosher or halal foods, respectively. Ergo, it could only be that the son had tasted forbidden fruit of the sea.
In reviewing the results with them, my body language made the father suspicious and he asked to look at the printout himself. He said, "Doctor, it is my understanding that you only become allergic to things after you have already been exposed to them." I nodded. He turned to his son and spoke to him firmly but kindly in Yiddish. I couldn't contain my curiosity and asked him to tell me what he had said. He answered, "How did it taste?"
