Negative allergy tests - but reacting to foods

[fuchsia0703]

DD15 has recently tested negative to pinprick tests for cows milk and soya. However when she eats these she suffers tummy pains more or less straight away, followed by headache, tiredness, sinus pain for a couple of days .. finishing up with huge "black eyes". Particularly in the case of soya where it is easy to miss something in prepackaged food, we have had a couple of recent instances where she has eaten something without being aware of it and has then reacted to it .. so i am convinced. Saw Paed yesterday .. he says he is sceptical .. feeling she has convinced herself she feels this way .. but to my mind that is rubbish. I am interested to get other people's views on what our next step should be ... thanks.

pinpricks tests for allergies,

there are other things such as lactose intolerance (body lacks enzyme to break it down into absorbable materials so it acts as laxative or just gets fermented), may have candida so starches and sugars get fermented, may have lack of enzymes to break things down (chinese people often lack enzyme for getting rid of alcohol so hangover after half glass of wine. Migraine after chocolate and cheese
All are really food intolerances rather than true allergies

Yep -I'm with astronomer.
Milk allergy is usually an allergy to the proteins, whereas intolerance is to the sugars part (lactose).

DH is not allergic to milk products but definitely intolerant to them. He can have small amounts only. (He is Chinese and definitely lacks the enzyme to break down alcohol as astronomer explained - but upside is he is always designated driver).

DH sometimes has rice milk instead.

she is def not lactose intolerant. DH had that year's ago and we knew all about the enzyme. Wetried the drops first thing and she stillsuffered. The most difficult thing is the soya rather than the dairy because it is hidden in so many things.

sounds like you might have to go back to home baking etc. Can't use prepackaged food here as DD has onion problems and they seem to be in everything
