As there is history of cough 4-5 times in a year and this time also there is spasm, it suggests the possibility of asthma.
A proper workup is needed to make the diagnosis of asthma like serum IgE level and pulmonary function test. If investigation suggests then long term treatment may be needed to manage asthma.
As eosinophil count
is against asthma and there is predominant lymphocytosis
with raised ESR, proper clinical and laboratory evaluation should be done to rule out other possibilities of cough like tuberculosis
and chronic bronchitis
