What does a cortisone shot do for a sinus infection?

A cortisone shot can help reduce inflammation in the sinuses, alleviating symptoms associated with a sinus infection, such as swelling and congestion. By decreasing inflammation, the shot may promote better drainage of mucus and improve airflow through the nasal passages. However, cortisone shots are typically not a first-line treatment for sinus infections and are more commonly used for chronic sinusitis or severe cases. It's important to consult a healthcare professional for appropriate treatment options.
