Allergies occur when your immune system is triggered by envirionmental factors it should ignore--for example, pollen in the air, or dander on a cat or dog--and creates cells to fight against them. An allergic reaction typically causes itching, congestion, or drainage, and ...Read more
Avoidance: As with any food allergy, the only treatment is avoidance. However, if the allergy is mild (e.g., little more than itching in the mouth when eating it), it may be a cross-reaction from a ragweed allergy. If that's the case, allergy injections will very likely make the itching go away. See an allergist for skin testing, so you can find out what is really going on and what you can do about it. ...Read more

My son developed hives and I wonder if it was because he ate some green bananas. Can hives be caused by a banana allergy?
Generally not: Hives due to food allergy will typically start between 10 and 60 minutes after eating a food, and last for several hours - typically gone by the next day. They will not come back after that, unless the same food is eaten again. Recurrent hives regardless of any recurring ingestion or exposure should be investigated by an allergist. ...Read moreSee 1 more doctor answer

This may include itchy mouth and throat, vomiting, hives and itching all over, swelling of the tongue or throat, asthma attack and allergic shock. Isolated stomach reactions to foods aren't allergic and dont carry the risk of shock. There are no allergy tests for this. ...Read more
Allergic Shinners: I assume you refer to dark circles under the eyes. These are called allergic shiners, but they can be caused by multiple things. They can be caused by a back flow of blood and dilatation of blood vessels due to congestion in the nasal passages. Any allergen can cause this and general allergy testing can determine this cause. Other causes include natural color, congestion from other causes. Etc. ...Read more
If anaphylaxis to food is so rare how come it seems to be pretty common when researched? If a blood test for food allergy was neg should you worry?
Took an allergy skin prick test for 32 common allergens. All were negative except control. Still have copious secretion in nose every day. What next?
Sinusitis: Sinus infections are a common cause for excessive post-nasal drip. This diagnosis is commonly missed by physicians who mistakenly believe that clear nasal discharge is definitive proof of the absence of infection. A cat scan of the sinuses might be needed to detect a low grade chronic infection. ...Read more
Blood test for common food allergies negative does this mean there wont be any reactions to food or anaphylaxis?!
Maybe,maybe not: The test would suggest you have no indication of an allergic response to the items tested.This would suggest you will not be troubled by a bad reaction to those items for your life, but you can develop a food allergy or intolerance later in life. Most food allergies are not of the anaphylaxis type, but produce hives or other symptoms. ...Read more
