<s>[INST] When I walk outside and breathe in cold air my chest begins to burn and I get out of breath. I spent several years in ND in the oilfieldand worked in extremely cold conditions butnever had a problem until just before I came home. I do have asthma but it usually only acts up during allergy season. [/INST] Thanks for your question on Health Care Magic. I can understand your situation and problem. By your history and description, in my opinion, cold actually triggered your asthma and caused you bronchospasm. This bronchospasm can cause breathlessness, coughing, wheezing etc. If it is severe and also involved trachea than burning central chest pain is also seen. So in my opinion, you are mostly having cold triggered asthma attack. You need inhaled bronchodilators and inhaled corticosteroid with antihistamine drug. So consult doctor and discuss all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
