Need Help with the nose problem and Low D

[Friendlys]

I'm having problem while i'm playing or actually practicing. I recgonize that when i'm blowing out
What happen is when i'm my nose is stress and the longer i play it get worse and worse and then
palaryze(I don't know the proper word sorry about the language)

I know that it's not a good thing here and i want to know why i'm feeling like this and how i solve this problem

One more problem I found that i can hardly play the Low D while i can play another low note
When i try to play low D it usually come to middle D

If you have any exercise to solve these problem feel free to tell me I really want to improve my skill
Thx a lot^^

I don't quite understand the problem with your nose. Can you try explaining it again?

Can you play a low C? If you are having trouble with low D, but other notes like low E or F play OK, you probably have a leak on one or more pads. Have you asked another flutist to try your instrument or have you had a flute technician check you flute?

I don't know the word to describe this thing with my nose (I try with Dictionary and it told me "pins and needles")
It is a state that you can't move or control one of your body like leg or hand for a short time(5-15minutes) but for me it happenwith my nose
I don't sure that whether it happen because i try to hard to control my embouchure.

Ah and about the Low D I try to experiment some thing what happen is i can play low note but not quite accuary
(I mean sometime i can but sometime i can't ) But what bother me is when i play low like start from low B to Low F
The Low D note is always go up to the middle one.

That make me confuse what happen. Is it happen to every beginner or just me

Thx for helping
P.S. I'll try experiment many thing as i can and hope i figure something more and i'll tell you later
