Suggest Treatment For Severe Sinusitis

Hello Doc, i have severe synosytis. my nasal bridge is curbed and i sneeze every morning after i wakeup. and any strong smell or little dust makes me sneeze for several times continuously. it is about 10 years i had a nasal surgery to fix the nasal septum growth that caused sinus blockage (as my surgeon said) and i passed about 4 years without any serious complain about headache or abnormal sneezing but from last 2 years the same symptom develops and i fell ill due to acute cough and headache periodically (in every 3/4 months i had to take antibiotic for sinus inflammation and cough (i am a regular smoker). Now doctor, please tell me if there is any permanent solution to get rid of this serious problem. It seems surgery is not a solution as i went through it but still the same problem persists! looking forward to get advice from you.. thank you. zahedeen
