Nasal blockage with watery discharge is commonly seen in conditions such as the common cold or allergic rhinitis, in which the nasal lining becomes inflamed, leading to congestion and a runny nose. These are usually mild and self‑limiting. Simple measures such as staying well hydrated, steam inhalation, and avoiding allergens or irritants can help relieve symptoms. If the problem persists, worsens, or is accompanied by fever, facial pain, or breathing difficulty, it is important to consult a doctor for proper evaluation and treatment.
