Hi. I understand your concerns. You will need to undergo a detailed examination and investigations. You will need to undergo pulmonary function test which is needed for diagnosis and also to assess severity of bronchitis based on which treatment can be started. stop smoking before it causes you any more harm. Consult a pulmonologist for the same. Hope your questions were answered. thanks.

I think you may have acidity problem and probably breathlessness is due to acidity.. try tablet pan 40 mg daily empty stomach for 10 days and if no problem recurs you have solution to your question.. stop alcohol
