If you have symptoms of a sinus infection, it is recommended to consult a medical professional for proper diagnosis and treatment. Sinusitis can be caused by a bacterial or viral infection, so it is important to determine the cause in order to receive the appropriate treatment. Common symptoms include nasal congestion, nasal discharge, fever, and coughing. It is important to seek medical advice if symptoms persist or worsen after a certain period of time. In the meantime, there are over-the-counter products and measures that can help alleviate symptoms, such as expectorant syrups, cortisone nasal sprays, and saline products to hydrate the nasal passages. Resting, staying hydrated, and taking care of oneself are also important in managing sinusitis symptoms.
