I expect a house-caused allergy to get better or worse as you exit or enter.
Not necessarily. If you were going from pristine-nose into allergen-house-of-doom then it might be as obvious as if you inhaled a load of pepper. But IME if you were to encounter an allergen when you already had a sub-clinical-allergy or minor lurgy, then the onset might not be anywhere near as sharply defined, and it can be hard to spot the culprit.
And as for it going away when you remove the allergen - hah, I wish! Can take days to recover. And you have to make sure you don't have any lingering in your hair/clothes etc.
