Is it normal for ears to pop when they get water in them from a sinus flush

[mikes425]

Hi and thanks for any help!  
I am a performer with CT Scans indicating 50+% mucous retention/blockage of
sinuses, including Sphenoid sinus.  No headaches or runny nose but sensation of congestion
for about 6 months affecting my voice resonance - and CT of sinuses were the only thing that
revealed considerable blockage in frontal and sphenoid sinus.  

As an actor I felt I knew all the usual ENT protocols/advice having done most of them for decades.
I do a lot of water,  mucinex and flonase and have been on allergy shots for  a long time mainly for
dust mite, and secondarily some ragweed & tree.

Lately I have done a few courses  of oral corticosteroids & antibiotics yet these don't seem to
be getting rid of the impacted mucus.  I want to reverse this condition and avoid surgery.

SInce this blockage was all new to me I started studying about sphenoid sinus and found the 'flip-turn' sinus flush discussion on this site.  I have done the NeilMed sinus rinse and Neti Pots regularly but it doesn't
seem to help with the deeper Sphenoid sinus area so i tried this flip flush  a few times this past week.  

When I fill nostrils with saline solution with the head back, I feel the liquid filling my ear canals - kind of
the way you experience water in the ears when under water - but of course in this case it's from the "inside-out"...and the  ears pop at varying levels plus i feel pressure shifts when the solution is moving...when I'm
tilting the head or rising up... and when gently blowing the nose sometimes..

I just wonder if this is normal with this procedure,  and okay to keep doing.   The ear feels blocked for awhile after two or three repetitions... and left ear tends to feel more closed or full - but hopefully it's fully opening up
again during the course of the day.  

I hate to not be able to do this technique, because so far it's the only thing i've found that is said to deliver the saline into the sphenoid sinus area -- to hopefully start breaking down material there --  vs. the standing method
of nasal rinse with the Neil Med bottle.  

I sincerely appreciate any advice or other suggestions to try.

Thanks very much,

Mike
