I am frequently suffering from shortness of breath and wheezing,specially at night. I have always suffered from funny nose and frequent colds since childhood. But since the last two years I have started wheezing too. Sometimes its so loud that I wake myself up from sleep. doctors have prescribed me montelukast,fexofenadine,betamethasone, and a cough syrup comprising of Ambroxol Hydrochloride Guaiphenasin and terbulatine Sulphate Syrup. My problem does not persist when am taking these drugs. But they come back when I don't. I also hav minute chest pain,please help
