an ent doctor would have advised you to undergo endoscopic sinus surgery and septoplasty. surgery is the treatment of choice because your problem seems to be chronic (from longer duration). if you do not want surgery then you can take nasal spray (a combination of steroid and antihistamines) for a month mucolytics for a week and antibiotics for 14 days. early morning jogging is really good for patients having sinusitis. please follow the advice for a month and check if you have any improvement in your symptoms. since the pollution levels are high in your locality i would advise you to do exercise and jogging at home itself. for further information consult an ent otolaryngologist online --> <link>
