Hello doctor my son 3yr 11months has on n off cough problem from few months, these cough syrups which doctor gives just give temporary relief. Again it's the same, our paediatrician is not ready to even take chest xray n see wats the real cause of this cough. Few months back he was also on inhaler of budecort n levolin. Now on cough syrups of relent plus and macberry xt, but still no relief, I want to no if there is any tests to do to confirm wat is causing this cough problem, I am fed up of this, please prescribe any permanent solution or tests to be taken for this n find the real cause.
