Hi and thanks for the query,
The onset of these symptoms especially under cold
conditions could still suggest an asthmatic or allergic terrain. It s true you do not have a history of asthma. Bt it would be worth investigating and knowing whether you don not have a family history of asthma or other allergic conditions like allergic rhinitis
A clinical examination in search of wheezes and other respiratory symptoms lung lung crackles and a condensation syndrome
could be important.
Blood tests could reveal either raised white blood cells suggesting an infection or high eosinophil
bloods counts, pointing to an allergic or asthmatic terrain.
A chest X ray
could be useful in ascertaining the nature of the lung tissue and size and aspect of the heart. Lung volume measurements could be asked to ascertain and further investigate asthma.
Consulting a pulmonologist for proper evaluation and management is my advice.
thanks and best regards,
