None of that relates to the nose.
And if it is only on blowing then your doctor is most likely correct.
Test your humidity in the house.
It should be at least 40 %...not above 50.
You could also get a unit just for the bedroom and this should help.
The other thing that gets missed is chronic sinusitis.
The only way to really rule this out is a CT of the sinuses which takes bout 3 minutes.
People stay sick for years when this is not done, as a drainage procedure is often needed to get well.
Follow up with ENT in this respect.
