Hello,
Thank you for asking your question at health care magic.
Since your mother has history of coughing episodes on exposure to trigger factors and long history, I would encourage the possibility of
Cough variant asthma.Asthma occurs due to constriction of muscles in wind pipe(bronchi).
If a patient comes to me with similar complaints, I ant to get a pulmonary function tests and chest
x ray as first step.More investigation may also be needed depending on initial results.
I recommend that your mother consult a pulmonologist/
primary care physician to get the evaluation done.
Meanwhile avoid any triggering factor for the cough.
Asthma is treated with
salbutamol inhalor , corticosteroid inhalor and more medications as needed according to initial response.
Hope I was able to answer your question
Please feel free to address any more concerns
Regards,
Dr.Lekshmi
