COUGHING
The character of the cough is also instructive. A frequent, loud, nearly painless cough, at first tight and later loose, is heard in bronchitis. A short, tight, suppressed cough, which is followed by a grimace, and, perhaps, by a cry, indicates some inflammation about the chest, often pneumonia. There is a brazen, barking, "croupy" cough in spasmodic croup. In inflammation of the larynx, including true croup, the cough may be hoarse, croupy, or sometimes almost noiseless.
The cough of whooping cough is so peculiar that it must be described separately when considering this disease. Then there are certain coughs which are purely nervous or dependent upon remote affections. Thus the so-called "stomach cough" is caused by some irritation of the stomach or bowels. It is not nearly so frequent as mothers suppose. Irritation about the nose or the canal of the ears sometimes induces a cough in a similar way. Enlarged tonsils or elongated palate or throat irritation may also produce a cough.
