Welcome in H.C.M.
I had carefully read your query regarding prolong cough, and tried to co-relate your symptoms ultimately I would like to suggest you to get yourself investigated on the line of chronic cough
.Though you have wheeze along with cough which favors the bronchospam. You should do-
1- X-Ray chest.
2- Culture and sensitivity of sputum.
3- Sputum for AFB and gram's stain.
4- Respiratory function test.
Till the reports of investigation will be available and you are in waiting you may take cough syrup having mucolytic
to get some relief symptomatically.
