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.

Difficult: Alot of the symptoms of a cold and allergy overlap. However, allergy does not give a fever and cold will resolve within a week or so.
Dr. Nayla Mumneh

Cold and allergies: Colds usually come with systemic symptoms of body aches and low grade fever. With allergies you generaly feel well except for your nasal symptoms.

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.

Big differences: Colds are due to viruses and are contagious but limited to less than a week. Allergies typically have itching (nose, eye) and sneezing as common symptoms. Symptoms can continue through a pollen season or for months or years (if indoor allergies). Allergies response well to treatment with medications and allergy injections. An allergist can assist in identifying if there is an allergy.

Allergy or cold: Colds may last one to two weeks, with runny nose, nasal congestion, cough and sometimes fever. Allergies may be similar but often last longer and there is often sneezing, itchy eyes and nose, clear watery mucous. If in doubt see a doctor for proper diagnosis and treatment. Allergies tend to be chronic or recurrent and are often worse at the same time of year.
