Talk to General Physician on Blocked Nose

Assalam u Alaikum, Doctors

I’ve been dealing with a blocked nose for about a month now. Both sides don’t block at the same time, they take turns. The mucus is transparent and does come out when I blow my nose, but it never really “runs out” and I can’t get rid of it completely. I don’t have fever, pain, or other symptoms.

This has never happened to me before, and there haven’t been any changes in my lifestyle, environment, or routine. I did visit some ENT specialists who said it’s nothing, but the problem hasn’t gone away. The only time I felt complete relief was when I used Xynosene spray (xylometazoline), but it only lasted for one night. What can I do to make it better?
