i am 47 years old and i am normally very healthy for the last  two weeks i have had a odd pain in my lungs that comes on fast when exposed to cold air, / aircondition room when leaving the outdoors. The pain is directly related to breathing and goes away when i get to warm air. I utilized a warm air humidifier in my room to sleep or i would wake up from this pain/ shortness of breath. i have no cold symptons other  than the chest pain but no cough, could this be asthma?
Thanks for your question on Chat Doctor. I can understand your concern. Yes, this can be due to asthma. Asthma is allergic Airway disease. You might be allergic to cold air and on exposure it causes bronchospasm and all the symptoms of cough, breathlessness, chest tightness etc. So better to consult pulmonologist and get done clinical examination of respiratory system and PFT (pulmonary function test). PFT will not only diagnose asthma, but it will also tell you about severity of the disease. And treatment of asthma is based on severity only. You may need inhaled bronchodilator (formoterol or albuterol) and inhaled corticosteroids (ICS) (budesonide or fluticasone). Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
