3. Could my cold symptoms actually be allergies?

If you are sniffling, but not achy or feverish at all, you may very well have allergies. Also, if your symptoms last longer than two weeks, and you also have red, itchy eyes, the evidence points to allergies. However, it's often hard to tell because people with allergies and asthma are more likely to get colds. They may already have inflamed and irritated lungs - so they are less able to fight off a cold virus.
