How can you tell if a rash is an allergic reaction?

Answer 1

Allergies are the result of your body "fighting off" what it mistakenly believes are harmful chemicals. In a normal result, your antibody cells destroy viruses and bacteria which invade your body and could harm you. In an allergic reaction, a harmless substance - usually something you eat or something you touch - sets off the same reaction from your antibodies. This causes an easily-recognized set of symptoms in pretty-much everybody. I have put them in order based on how dangerous they can be. * Sneezing and watering eyes * Itching (either all over the body or just on the area contacted) * Redness and a bumpy rash (hives or wheals are what you call the bumps) * Swelling of the throat and mouth * Difficulty breathing Each allergic reaction may produce one or more symptoms. Some people sneeze and itch whenever they get near an animal. Some people are fine with animals, but get an itchy rash if they eat strawberries. The first three symptoms can easily be treated with over-the-counter allergy medication like diphenhydramine (Benadryl is one brand name for this) - these kinds of allergies are seldom dangerous, and usually disappear once you take the medicine. If you should have ANY trouble with wheezing, feeling as if your throat is closing up, or swelling in the mouth area - go to the nearest emergency room and tell them you are having an allergic reaction with these symptoms. These are symptoms of a life-threatening reaction called anaphylaxis (an-uh-fil-AX-iss). Anaphylasis must be treated by a doctor as soon as possible, because it can cause you to stop breathing and die. This is the reaction that you hear about most commonly in people who are allergic to beestings. The bee venom is actually injected into the body instead of being contacted like the less severe allergies, so it can cause death within minutes! Some people get anaphylaxis after eating certain foods. The best way to treat any allergy is to take diphenhydramine as soon as you notice any discomfort. However, if you have the severe kind of reaction, don't waste time finding a drug store - go straight to the E.R.

Answer 2

The best method for diagnosing food allergy is to be assessed by an allergist. The allergist will review your history and the symptoms or reactions that have been noted after food ingestion. If the allergist feels the symptoms or reactions are consistent with food allergy, he/she will perform allergy tests.

Answer 3

if you get it after exposure to something you are allergic to. Like avocados or an animal.

Answer 4

if someone eats a nut and their throat swells and their eyes water then they're allergic to nuts :)

Answer 5

It depends on the coupon. Many coupons are for smaller sizes, but there are coupons for larger (or any) size packages as well. The coupon should say which size packages(s) it can be used for.
