Wow FG. I do hope you are feeling better. I too have terrible sinus troubles. Although I don't have a deviated septum as you do, I do have a cyst in my sinuses. They cause blockage and then I get infections.

Surgery??? No way. Not going to happen unless the cyst get really bad.

The cyst shows up on all my MRI's and CT scans.

As for pneumonia - I went through a period of about 2 years where I had pneumonia on and off. I even ended up with pluerisy. OUCH! Most the time I didn't know I had it. The pneumonia always coincided with a sinus infection. Ultimately, I went to an allergist who not only diagnosed the allergies but ran a tither and found that I don't have the antibodies to fight 4 of the most common pneumonias. So, I got the pneumonia shot, take my allergy medicine, Flonase, and daily nasal lavages (saline rinses - not the neti pot). For the most part I do well with this regime.

I wish you the best and am sorry you are feeling so poorly.
