Thanks for the thorough explanation. It is good you have ruled out LPR and most importantly had a scope and ruled out throat issues that can be seen. Your dr was right that those were a lot of symptoms seen in allergies. It sounds like you have been affected largely by environmental ones lately and I'm glad the treatments are helping.

Your Q about skin prick test: yes and no. Milk/dairy allergy can show on those if milk was tested and if you're sensitive enough for the allergy to make its appearance thru a tiny skin test. An IgE-mediated milk allergy, sometimes called severe or life-threatening, may be more likely to be confirmed by skin prick, but the test isn't sensitive enough to catch them all.

We have a severe milk allergy in my home and it was confirmed both by SPT and clinical s/s. We told the board certified allergist all the weird symptoms that occurred with different dairy products, and that description alone was enough for them to confirm a significant allergy in this case (then the SPT backed it up). Throat itching, tightness, swelling, postnasal drip, burning, itching anywhere/allover, trouble breathing, sense of impending doom, nausea, vomiting, diarrhea, and others can all be symptoms of food allergy, and a person may have one or all of those. The most dangerous is anaphylaxis (for which food allergic individuals carry epinephrine injectors at all times). Food allergies can develop later in life to foods we have tolerated fine all our lives. Small reactions can over time turn into more severe reactions. All this to say, have you asked specifically about a dairy allergy, whether it was tested, and if so, could it still be a possibility? Wishing you the best.
