An embarrassing runny nose can seem to strike at the most inconvenient moment. You have probably found yourself minding your own business when suddenly your nose begins to drip like a broken faucet, and you think to yourself, “Where are the damn tissues!?”, which inevitably sends you scrambling to the restroom in a flurry of nose activity. A runny nose isn’t just a symptom of looming sickness. It can also be a result of the foods you eat or even unknown allergies that you may have. A nose can run for all sorts of reasons, including infections, allergies, and irritants.
