Help, URGENT need a specialist in allergies

My collegue broke out in a rash and started to faint and vomit, they can't figure out what it is, its been 3 days! Who is the top allergy specialist in Hong Kong!

Is your friend in Hong Kong? It sounds like he narrowly avoided a life threatening emergency. He must figure out what the reaction was to and must forever be obsessed with finding and staying away from the food that caused the allergic reaction. (But also be aware that some infections can cause rashes, and even RAST testing is not the be-all-end-all; you must be a real sleuth sometimes to figure out the culprit.) My family has used Dr. John Simon for food allergy related issues, and he is one of the best doctors -- most thorough, thoughtful, insightful, and attentive -- I've ever seen. But somebody else on this board once posted that they didn't like him; I guess it's a matter of preference. I don't have his contact info at this moment, but you can do a search here because I've posted his info before in other posts. His diploma is from Oxford. My child was hospitalized at Adventist, and I was very happy with that hospital, as well. I've heard expats say that if you have a real emergency, get yourself to Adventist and just get processed through the ER if necessary. But in terms of food allergy, the reaction takes some time to get over, like ten days or so. I'm not MD by any means but our emergency kit includes epinepherin injection, antihistamines, and prednisone. I'm not going to say how those are used because they are powerful drugs that must be used only under medical supervision, but the doses for acute, severe allergic reactions are large, specific, and even with massive amounts of medication you can count on a severe reaction really taking the wind out of someone's sails and taking many days to recover from. Then, the medications themselves can take some time to recover from in the doses prescribed. It's serious business.


When you say "they can't figure out what it is," I assume you mean they can't figure out what food. Food reactions do not always show up on tests. You must follow an elimination diet, and then just like a baby does add one food at a time adding only one food at a time every four days or so and note symptoms. But I'm not sure a food allergy would cause fainting and vomiting? Unless it were from lack of oxygen to brain from an anaphylactic attack (flooding lungs with fluid, closing up breathing passages). Best of luck.
