it could be possible to associate the cough to allergies, but I think other common causes of chronic cough
must be evaluated. The first exam that will act as a triage is a chest X ray. Infectious causes like pneumoniae, pleurisy
, aspergilloses and some heart anomalies could lead to breathing difficulties.
It is interesting to carry out a sputum exam especially with chronic coughs. Pulmonary Tuberculosis
must be excluded in this examination, and presence of specific allergic bodies called charcot Leyden s bodies could suggest an allergic origin.
Blood tests like measurement of Immunoglublin E levels and a complete blood count
, to show a rise in levels of Eosinophils to suggest an allergist origin.
I suggest you visit your internist/pulmonologist for this allergic cause to be evaluated, and other common and serious respiratory tract
infections like pulmonary tuberculosis be excluded.
Thanks and hope this helps,
