Sinus infections can be one of the most difficult to treat because there are so many small crevices where pools of infection can hide out.
And sometimes it takes a long course of antibiotics to clear up completely much longer than a typical bronchial infection.
One time I had such a long standing infection which persisted that my regular Dr. was considering sending me to a specialist to put a scope up there to see what was going on. He told me to call my regular allergist first to find out if he did this procedure.
However, my allergist, being the conservative type said to give him a crack at it first since scoping is basically an invasive procedure.
He put me on one of the strongest super antibiotics at the time (Cipro) along with a strong STEROID nasal spray with strict instructions to use it no longer than a week to ten days.
Well, that did the trick with no scoping necessary, fortunately.
It sounds to me like your hubby should be seeing an ENT specialist since the rest of everybody hasn’t been able to get a handle on this.
You need someone with more experience and competency than the average Doc. Find put who has the reputation of the best ENT guy in your area.
(Nurses are a good resource since they see so many Drs. at the hospital and word gets around about who is the cream of the crop. That’s what’s needed here IMHO.
My advice is based upon years and years and years of dealing with sinus and bronchial infections and the advice of my Allergist (who was the head of his dept at the local hospital) and a Pulmonologist whom I layer saw who did a thorough evaluation of my whole history and pointed out to me on X-Rays how narrow my sinus passages were and how that was the seedbed of infection.
He was the one who advised me to regularly use a Decongestant (Pseudoephedrine) in addition to the antihistamine explaining that antihistamines dry things up but decongestants promote drainage. (For all those years I had just thought they were pretty much the same. Boy was I wrong.)
And about a year or so later, I realized that I had only had one bad infection whereas before I had an infection about every month or two.
A competent specialist is worth his weight in gold. Find one.
And one more bit of advice for the future regarding the polyps. Do some research on a procedure called “Balloon Sinoplasty” and ask the specialist you see for more info.
This is a fairly newer procedure and is far more successful and far far less invasive than standard sinus surgery (frequently used to treat polyps, but is EXTREMELY painful with a 30% fail rate.)
The worst consequence from Balloon Sinuplasty (done by a competent experienced specialist) is that it doesn’t work the first time around. It can be repeated without any serious side effects.
Anyhow, I hope some of this info helps. I know how miserable it can be dealing with sinus infections. But it’s not necessarily run of the mill stuff. Sometimes it requires the expertise of a specialist. Please seek one out.
Looking back, I realize how fortunate I was that I ended up with two of the best. Plus I had a regular Doc who realized when it was time to refer me to them. I was lucky to have gotten really competent diagnoses and it’s now rare (rather than commonplace) for me to get either a bronchial or sinus infection.
But I won’t stop taking Pseudoephedrine for drainage no matter how difficult it becomes to get.
Anyhow, I hope this gets resolved for you soon.
