How Do Sinus Infections Differ from Colds?
Sinus infections and colds share several symptoms, making it difficult to differentiate between them. However, there are key differences. A cold is caused by a viral infection that primarily affects the upper respiratory system, leading to symptoms such as a runny nose, sore throat, cough, and mild fatigue. It typically lasts for 7 to 10 days and is self-limiting. Sinus infections, on the other hand, occur when the sinus cavities become inflamed and infected, often due to a cold or allergies. The primary symptoms of a sinus infection include facial pain or pressure, nasal congestion, and thick, discolored mucus. While both conditions involve a stuffy nose, sinus infections are more likely to cause intense facial discomfort and may last longer than a typical cold.
A cold usually resolves on its own, but a sinus infection can lead to more severe symptoms, including a fever, persistent headache, and chronic congestion. Sinus infections may also result in symptoms that last beyond 10 days or worsen after initial improvement. In contrast, a cold typically resolves within a week to 10 days. If symptoms are severe or if there is no improvement after a week, a healthcare provider may recommend additional treatments, such as antibiotics for bacterial sinus infections.
