Hi. I understand your concerns. You might be having allergy. You will need to undergo a detailed examination and investigations like chest x ray to look for infection. if it's normal then you will need to undergo pulmonary function test which is needed for diagnosis and also to assess severity of bronchitis based on which treatemnt can be started. You can consult me at my clinic at hebbal kempapura. Details are mentioned in practo. Consult a pulmonologist for the same. Hope your questions were answered. thanks
