Thanks for your question on Chat Doctor. I can understand your situation and problem. You are having upper respiratory tract involvement (sinusitis) and lower respiratory tract involvement (breathlessness). So possibility of allergic etiology is more likely. Allergy can cause sinusitis and bronchitis. So better to consult pulmonologist and get done 1. Clinical examination of respiratory system 2. PUT (Pulmonary Function Test). If PFT is suggestive of bronchitis then start inhaled bronchodilators and inhaled corticosteroid (ICS). Oral combination of antihistamine and anti-allergic Chat Doctor.  So consult pulmonologist and discuss all these. First diagnose yourself and then start appropriate treatment. Don't worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks.
