dd(7) has had an awful 'chesty' cough for a few months now,most of this year in fact.weve had at least 4 trips to GP who has listened in to her chest and said it sounds clear,no infection but will give her antibiotics just incase.cough is still no better,it sounds very crackly and on a morning it takes ages for her to clear her throat of mucus to be able to speak or eat properly. on top of this,for the past 3-4 days she has c/o feeling dizzy which is starting to worry me.obv im taking her back to the docs but does anyone have any experience of this,does it sound connected? should i be pushing for a chest x-ray? tia
