This sounds really dumb as I type it out

if you were allergic to it, you would break out in hives. being itchy, abdominal pain, anaphylactic shock.... stuffy nose would be least of your problems

Not everyone reacts to things the same

I cant have diary as it gives me eczema

So you've never eaten chocolate? Ever?

But...

Is milk chocolate considered dairy?
What I mean is, does it have enough milk in it to affect my sinuses?
( I get stuffy and all that grossness when I have milk/dairy products)

Is jello a Fruit? But REALLY, why don't YOU just eat a piece and see...or better yet, ask an Allergist.

I have a daughter that has extreme reactions to anything dairy, even cross contamination. We have gotten really good at reading labels. Diary can be listed as many things.

There are many dark chocolate bars and dark chocolate chips that are dairy free, but not all of them, so read... read... read.

I'm here for you if you have any chocolate that needs eating

You can try switching to carobs if you're allergic to chocolate or cocoa. A friend of mine has cocoa/chocolate allergen and she switches to carob. May not taste the same as chocolate but pretty close I heard. I think they make carob bars these days. If there isn't any and you need a chocolate fix you can just make your own carob bar. It usually calls for a few ingredients like carob powder + coconut oil(to solidify). Heather from Healthy vegan had made some. I'll just link you to her webbie http://www.healthyveganrecipes.net/video/homemade-chocolate-recipe

Found these 3 on pinterest. Hope it would help you with your choc fix

Hiya. You mentioned mucus. Does it drip down the back of ur throat? I had this for years and decided that the mucus may be too thick so therefore I tried drinking more water. AND IT WORKED! If u do suffer with this problem and u need instant relief, suck on a cough lozenge - my previous doctor suggested this. He said it would cut thru the mucus and sure enough it did.

My son is allergic to colour additives 122, 123 and 124 red food colouring. I was never able to really narrow it down when he was a toddler but now he's 27 he tell's me that he knows as soon as he's had one of these additives as his gullet starts to feel sticky with mucus and he feels awful and nauseous. If he has enough of the additive he will vomit. Poor little bugger must have felt like rubbish when a toddler but unable to tell me. I've bought chocolate fish without a thought but of course the insides are pink; most of Gregg's Instant Puddings here in NZ have 124 additive so that wipes them out; and then of course there are the expected - raspberry soda, raspberry cordial, jellybeans (I think this includes the black ones as well). I bought some marinated chicken nibbles about 6 mths ago and sure enough the marinade had one of those additives in it.

My advice is to test, test and test yourself. From memory to do it properly you are meant to take urself off everything except the bland food such as potato so that nothing else can affect the test. Then you slowly introduce the suspect food. Try doing a search on the internet to see how to do this. I have but this one is different to the method I remember of many years ago LOL http://www.care2.com/greenliving/diy-food-intolerance-allergy-test.html?page=6#13685192409311&action=collapse_widget&id=9807424

Personally I think ur on the right track. Trust ur gut instinct - both my son and I did. GOOD LUCK!!

there are different classes of severity of allergic reactions, at the lower levels, you won't get all those symptoms. Anaphylactic shock is the most severe level, most people with allergies don't go into anaphyactic shock. Even hives and abdominal pain don't happen in milder allergic reactions. Stuffy nose and other cold/hay fever type symptoms are common with allergic reactions and in mild allergic reactions might be the only symptoms.... and hay fever is an allergic reaction to pollen, asthma can result from inhaling allergens, so some people who are allergic to pollen will get asthma as well as hay fever symptoms, but that does not mean that someone with only hay fever symptoms in response to inhaling pollen is not allergic to pollen, only that it's a milder allergy.

Mild allergic reactions are the hardest to track down in terms of what's causing them, because there's usually a delay between eating the food (or exposure to an airbourne allergen) and the symptoms. In the OP's case it sounds like she has a mild allergy to dairy, (but not that mild, seeing as the small amount of milk in milk chocolate can set it off), and she was clear of symptoms when avoiding all sources of dairy, but it suddenly came back after eating the milk chocolate.
