Re: sinus infection for 2 years
Agree wtih gcsjr re ENT and CT scan.
That's how my blockage was discovered & I needed a surgical fix (uncinectomy) for greater drainage. I was symptom-free days after surgery 3 weeks ago. Even tho I was on the right antibiotic before surgery (based on culture results), the physical obstruction & poor drainage enabled the sinus infection to thrive. The CT scan helped solve the mystery of why I wasn't healing.
Good luck to you. I hope you can find the source of your infection & a successful treatment.
