You could have either a cold or the flu or both. Or, you could have allergies. See the related questions for information about the symptoms of cold and flu.

An allergy is an entirely different condition than a cold or flu. The flu does not "hold" an allergy. Sometimes people with allergies are more susceptible to cold infections or infections in general because their immune systems are taxed by trying to deal with the allergen that is triggering the immune allergic reaction. Or, in the case of viruses like the cold and flu that enter your body through your mucus tissue in your eyes or nose and mouth, allergy symptoms can allow the virus easier entry to your body because they have irritated or damaged mucus tissues making them more easily penetrated by the virus. Allergies make your body think it is sick with germs but it isn't really. Cold and flu are caused by viruses, so you have an infection. The symptoms are sometimes the same or very similar but the allergic response happens when your body knows there is a foreign substance irritating you (e.g., pollen irritating the sinuses and eyes) but doesn't know that it is not a germ. Flu is caused by germs (viruses).
No. Cold and flu viruses are unaffected by cold or even freezing temperatures.
