My sympathies...chronic sinusitis isn't fatal but is life-changing, for sure. My sinus issues began after I contracted CDiff -- after a hospital outpatient surgery, I feel sure. It's worsened over a decade-plus, getting so bad 2-3 years ago that my fourth ENT, head of the department, first did a balloon procedure, which did nothing, then an antrostomy to enlarge the maxillary openings. On the heels of that surgery, I contracted Covid for the first time. Things have gone downhill since then. 2023 was bad. I was sick at least half the year -- PND, maxillary pressure, gag coughing, fatigue, dizziness, body aches. It would come and go and come back again. I just had thorough blood workup. Turns out my IgG and some pneumococcal levels are somewhat low, meaning weakened immunity. So is that why my body is unable to shake this syndrome? On the other hand, it occurs to me that maybe the whole thing is Long Covid (dizziness was my big Covid symptom). I'll be seeing an immunologist soon for yet another opinion. Anyone else believe their sinusitis is a manifestation of Long Covid? Thanks for any input!
