Avoid cold,oily and very sweet food as they increase mucus production.Drink lots of fluids (Warm).Hot tea with honey, ginger and lemon might also give you relief.Avoid smoke,dust and other pollutants. If after following the above measures,if still your symptoms are not improving,then it would be advisable to consult an Otolaryngologist Doctor.He/She will diagnose your condition by doing nasal endoscopy and CT scan if required and treat accordingly.
