Rhinorrhea is commonly referred to as a "runny nose." This condition typically occurs when the nasal membranes produce excess mucus, often due to allergies, infections, or irritants. Symptoms may include clear or colored nasal discharge, sneezing, and nasal congestion. While not serious, rhinorrhea can be uncomfortable and annoying, sometimes accompanying colds or flu, and can make daily activities challenging. Treatment may involve over-the-counter medications to alleviate symptoms, such as decongestants or antihistamines. It’s important to address the underlying cause for effective relief.
