If you are experiencing difficulty breathing, coughing (especially at night), slight nasal congestion, and headaches, it may be due to nasal congestion and nasal drainage. I recommend using a product like Sinus Rinse™ twice a day for at least 5 days to help reduce your symptoms. For ear pain, it could be related to fluid in the middle ear. After using Sinus Rinse™, you can try using a product like Otrivin™ to help open the canal connecting the ear and throat. Followed by a technique called Valsalva maneuver, which involves pinching your nose, closing your mouth, and blowing while swallowing to help drain the fluid from the ear. If the issue persists after trying these methods for 3 days, it is recommended to consult a doctor.
