I'm really worried because I've been dealing with shortness of breath, chest pain, sinus infections, and fatigue for the last four months. I've seen three doctors, but nothing seems to be working for me. I've tried medications like doxycycline, azithromycin, montelukast, deflazacort, trystep D, gudacef antibiotics, bronchodilators, and fluticasone nasal spray, but the allergy is just getting worse. My IgE levels have jumped from 250 in June to 1100 in September, and one of my nostrils is always blocked due to the sinus issue. I'm constantly tired and at random times my chest hurts. My X-ray, blood test, and ferritin levels are all normal, but nobody has done a PFT because of COVID. Why is this happening and what should I do next?
