I guess it may be too late to reply on this thread, but maybe others will read.
I had sinus issues for over a decade, which no netti pot, nose spray or allergy med could help. Everything from inflammation, post-nasal, and infections that required antibiotics. Most often I would end up having to take 2 full courses of antibiotics back to back to get only a marginal improvement!! I even tried about 6 different antibiotics over the years. Didn't matter. . . NOTHING really helped.
I finally got a CT from an ENT and found out it was not just a simple case of chronic sinus infections or allergies! It was 3 or 4 things: a deviated septum (I broke my nose years ago) concho bullosa and turbinate issues. I had never even heard of these things, except for the septum. Anyway, ended up needing surgery on all three things. Got the surgery and the sinus issues went away, BUT NOT right off the bat. It took a good 6 months to feel semi-normal and a YEAR to feel about 70% better.. . Meaning I got a few sinus infections during the first year of recovery (that required Augmentin.) The good news is the infections DID go away MUCH quicker than they did pre-op.. . no more 20 day antibiotcs ! I felt better in a week. Now, after 2 years out, I have had only 2 sinus infections, and they were much less intense and healed MUCH quicker than they did before I had the operation.. . So waiting only a month after surgery to see if you are much better is WAY too soon to judge it. Wait for 6 months to 2 years to see if you are significantly better than you were before surgery. In the meantime get a second CT scan to see if it looks better and also to check for any additional probs, such as enlarged turbinates, etc...You may want to get your CT scan from the Doctor that did the surgery and a second one from a different Doctor just to see if they say the same thing. Don't despair about waiting 1-2 years to see really good results, as you will be getting better and better, month by month, there should be small improvements. At least there was for me. Which is a friggin miracle, cuz usually I am that person that none of the doctors can figure out what's wrong with me. I.E my Chronic Fatigue that has completely disrupted my life for the last 12 years :/ But that's another story.. . .
I hope you all feel better soon.

I have had similar sinus issues that feels like a constant pressure between the eyes near the brain. My ENT said I had infected sphenoid sinuses and I went thru surgery to get them cleaned up.
Well here we are a month later after surgery and it feels the same way. So be hesitant if your ENT ops for surgery. Maybe get a 2nd and 3rd opinion.
Surmising your doctor correctly diagnosed you, your sinus infection seems to be in your upper sinuses. Antibiotics often don't work in sinuses, due to a lack of blood flow, and nasal sprays wont reach upper sinuses, due to gravity.
This technique uses gravity to flush out sinus infections, and is pretty safe for a person your age.

If you get no results after a few weeks of flushing, then it could be one of the other things you suspect.
At any rate, go see the ENT
