Hello - I've been diagnosed with dust mite allergy - however I notice that my symptoms (stuffed nose, swollen throat) are quite weak after I wake up in the morning, and generally become stronger as I move around. Symptoms don't go away when I am outdoors. This has been going on without change for a year.
1. Could it be that I am allergic to something else, not dust mites? They diagnosed me based on intradermal test, the skin ***** showed negative for dust mites.
2. How long (how many hours) after discontinuing contact with an allergen should symptoms go away?
