My only daughter,aged 12 Yrs+ right now and she is suffering from Allergetic Childhood Bronchial Asthama since at the age of 04 Yrs. Frequently she suffers in cold and cough. Everytime when our doctor's advised for some radiological and pathological investigations, it's doesn't reveals any abnormality in the report. What should i do next to free herself from this problem? Kindly help me Sir. I am a Radiographer Technician by profession and working in a reputed Diagnostic Centre in Kolkata since for the last 15 Yrs.
