I have a cough that is caused by the feeling of a dust particle in the back of my throat. I cough to clear the throat . It is a dry cough. But one cough often leads to more immediate coughing for 6 to 8 coughs. Sinuses are clear, no mucous. Very irritating. Age 67, no allergies, and in good health. Normal weight.
Hellos you mentioned that you are having" Chat Doctor.  This means either some sort of allergy or throat infection. When such type of patient visit I usually advise them to take dextromethophan + chclopheniramine male ate + guaiphenesine cough syrup (2-3 T S F three times in day). Take some dextromethorphan longer for throat clearance. Take some antibiotics like among clavulanic acid three times in day. This treatment will cure within 5-7 days. Avoidance of dust, mite, pollen, molds will help. Hot coffee also provide relief. Hope this will help you. Still no relief within 7 days, consult a physician and get his opinion.
