What is the difference in symptoms bteween a cold and allergies?

Keeps coming back: They are similar! Itchy nose, sneezing, nasal congeston, running nose, coughing, sinus pain/fullness, post nasal drip. No fever with allergies, though. And most with allergies don't 'feel sick'; but they do feel tired, fatigued, wiped out. Why? Because allergies, like colds, tigger immune responses that sap energy.

Sometimes difficult: but except in very severe cases of allergy, people don't lose appetite with allergy which is also not associated with a fever. Allergy may also be seasonal. Cold is more common when school starts and in the winter, allergy in the warmer months. Cold is not relieved by antihistamine which does reduce allergic symptoms. Hope these points are helpful.
