Pulmonologist,  's  Response
Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.

First of all no need to worry about lung infection or tuberculosis as his chest x-ray is normal. Cough variant asthma can also cause chronic coughing. And IgE can be normal in some asthma cases. So better to consult a pulmonologist and get done PFT (Pulmonary Function Test). If PFT is showing obstructive defect then it is due to asthma. He may need inhaled bronchodilators (formoterol or salmeterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone).

Hope I have answered your query. Let me know if I can assist you further.

Regards,
