As a service to hypochondriacs everywhere, here is a list of conditions that list “cough” as a symptom. I am providing this service free of charge. You may notice that there are some repeats (is it necessary to list “Dust mite allergies” and “Allergies” separate?). Some are just plain vague (“Lung conditions”). Just keep in mind that this is not my list.
