LOOKING SUGGESTIONS FROM WELL EXPERIENCE

Dear doctors Please no consultation ideas. If I find really experienced and specialised one in the same speciality then I will contact u via mail if mail I'd is given and pay your fees. I have little knowledge on diseases. Since last 4 weeks I am suffering from sinus and sinus associated nose block, congestion , very mild pleghm and very very rare cough. AND I am experiencing every year. Once mucus is come out though nose by forced blow then till next year I am free. Some years it clears in 2 weeks some years it clears after 2 months. Now I tried, sinarest tab n syrup, monticope, Allegra 120, azithromycine, steam inhale, betadin gargle. And home made syrups too Still it is sustained. I am sure it is not covid or I agree it is covid. I am not willing for surgery ot alternative medicine. Right now I am on tab bisoheart 2.5 mg, tab trigabapantin 100 and tab aztolet 10mg each 1 a day. Also i am having diet based IBS C. Please suggest a right medicine which has less side effects
