I have  since 10 years occasional congested nose which result in upper throat infection and before couple of years I became allergic to oily things which cause whooping cough with some times chest pain . The symptoms does not remain persistent if I take amocylin it goes away . But with simple allergies I feel congested chest and whooping cough again . By using duanase nasal spray I feel nose allergies go away but once I stop using it .I feel  nasal allergies again and then cough .. Should I first consult ENT or chest specialist.. thanks
