I get coughs occasionaly . its dry and cough a lot?

Need more details: There is a large list of things that can cause cough- asthma, reflux, allergy, sinus infection, nerve irritation, among others. A dry cough is less likely to be caused by infection than a cough that is productive. Try saine sinus rinse, guaifenesin, throat lozenges, antihistamines (e g loratadine), and otc "cough syrups." if it lasts longer than a couple of weeks, see your doctor.
