Hi Doc, I am having this problem of shortness of breath for last 3 years now. The problem is usually elevated when whether is more humid and its raining. I have been smoking for 8 years until last 5 months. I drink 2-3 times socially in a week as well. I consulted a specialist last year, and was told it is an allergy and would be trated over the period of time. For the last few days, the shortness of breath is severe and can not sleep also because of this. I am also having pain in right lower chest when deep breathing. I stay in a very humid place in the world (singapore) and one thing i have noticed that on a very humid day, this problem turns back with nausea as well. I consulted a doc few days back (General Physician) and he gave me some tablets (allergy and to clear the air ways). It worked for 2 days. The problem turned back again after a day. (Its raining again !!) what are the possible causes of this problem? Is there anything to be worried.what tests do you suggest me? Appreciate your help ! Thanks Doc, JayD

Hello Mr Jay. Thank you for asking at Chat Doctor. I guess you have quit smoking for last 5 months, and if I am correct, congratulations on that. It is a very important step for your respiratory complaints. From your history, I would conclude that you are having recurrent breathlessness, worsening on humid days. You may be having allergy to house dust mite or molds, which increase in concentration during humid days or pollen which are released during rainy season. I would suggest you to consult an Allergist-Immunologist who will take your detailed history and suggest allergy testing. He may suggest you allergen immunotherapy after allergy testing. If you have frequent shortness of breath, you may need daily controller medications (inhaled corticosteroids, montelukast, etc.)I would also suggest spirometry with reversibility testing. This test is helpful to differentiate between asthma and COPD (chronic obstructive pulmonary disease).  Apart from these, ensuring proper sunlight & ventilation in your rooms, avoidance of smoke-dust-air pollutants and regular breathing exercises will help you on a long run. Hope this will be helpful to you. Wish you the best of the health. Regards.
