What is the best trick to unblock the nose?

Good morning, ma'am,

Your best treatment will be nasal hygiene with a saline solution (Hydrasense, Sinus Rinse and others), which can be done as often as necessary during the day (no maximum), and at least 30 minutes before bedtime. It's a little uncomfortable but works wonders! I also suggest applying Vicks Vaporub to the chest, it can help unclog the nose, especially at night

I hope I have helped you, and I am available if you have any other questions!
