thanks for your query.
may be an early feature of asthma
for which i will suggest you to have a pulmonary function testing with bronchodialator reversibility to check whether there is any obstructive airway disease
or not. If present you need to be treated with proper asthma medication
i dont know whether you have a family history of asthma and atopy
or not. because these will be more suggestive of asthma.
dont be panicked. take alprazolam 0.25 mg daily at bed time for 2 weeks to cut off your anxiety
. along with that test i also suggest you to go for an ECG and TMT.
i think u will get some clue from these tests.
