Dry Cough: Often a 'dry cough' is caused by a sinusitis thats causing an irritating post nasal drip. Try some benadryl (diphenhydramine) (particularly at night as it may cause some drowsiness), gargle with some salt water and menthol. If the PND is from allergic reasons then claritin or zyrtec work well.
