How To Treat Bronchitis And Maxillary Sinusitis?

Hello, i had cough and cold (heavy mucus) and chest cough for 1 and half month. Initially Doc treated with antallergic tablets like navision, alaspan. After some days I noticed blood during coughing. Informed doc and he aksed to go for blood test. It is normal except .5K less RBC and Lymphocytes increased by 1. Blood was only for 2-3 days (Noticed 4-5 times). Doc (ENT) said its may be because of some injury because of violent coughing. I took Pulmonary test too which shows everything normal. His diagnosis was that i have bronchitis and because of that I have cough. After one month he prescribed the tablet for bronchial asthama and specific medicine for cough ie rotacaps- Levolin for one week followed by another rotacap seroflow (250MG) . I was filling better except nose used to get blocked in between. Then all of a sudden, i again started sneezing (End of 5th week) and nose secretion begin again (Its was think and sticky). Again visited the doctor. he doubted some infection in the sinuses. Asked to go for a CT scan of PNS for Allergic Fungul Sinusitis. Scan shows that Maxillary Sinuses are filled with fluid. Scan shows that its quite significant. Doc mentioned that we haven t addressed Sinuses problem so far and because of that it kept growing in the sinus (told in simple language-- may be some other reason in medical terms). After knowing this now I am prescribed with Roxid-M tablet (1---0---1) for 7 days and Syscan 150mg weekly once for 3 week. Also I was using nasal spray Metaspray all these days. Now the enw spray is prescribed - Nasonex.. 2 puffs every night. In addition to this... Nasoclear Saline 3-3 drops twice a day for 2 months. I am in countinuous touch of the doc and he is well known ENT specialist and I am seeing him for quite a long time (More than 3 years). Every time i get cold, my cough sometimes last for more than 1 month and many times it turns into dry cough. But this time I had wet cough i.e. it was never dry. Just wanted to know if this is a normal problem or I need to do any further tests. As per teh doc, In my maxillary sinuses the air flow is too minimum as shown in the scan. and thats why its significantly contributing to the trouble. He also advised to start breathing exercises (Jal neti etc) for better results. Observation in CT Scan: Frontal sinuses- Clear Ethmoidal Sinuses: Soft tissues seen in the anterios, middle and posterios ethmoid sinuses Maxillary Sinuses: Polypoidal Soft tissues seen billaterally Spenoidal Sinuses: clear Osteomeatal Complexes: involved bilaterally Nasal turbinates: Noral Nasal Septum: DNS towards right with Bony Septal Spur Nasopharynx: normal Orbits: normal Impression: 1. Bilateral ethmoidal and maxillary sinusistis changes with involvement of the OM complexes 2. DNS seen towards the right with Bony septal spur Observations in Scan- My Septum is deviated right with bony spur. Please advise.
