my girl is 4 yrs old past 25 days she had cold and cough so after showing her to doctor he told to use antibiotic amoxy clavum bid syrup we have used for 1 week it's ok at that time but again after 1 week she was sick with cough morning times she was ok but at night times she was continuously coughing it's been almost 1 month doctor told that to use nebulizer for 1 week it will be ok along with cough syrup. xray was also done to see whether lungs are clear or not. Lungs was also clear then what may be the reason that still coughing at night times daily since 1 month I can't see her like that plz tell the solution for this.
