Throat and Chest.-- In chest affections, when talking, reading aloud, singing, etc., causes a very weak feeling in the throat and chest --causes an exhausted, "given out" sensation, and produces hoarseness; using the voice produces weakness in the arms between the elbow and shoulder, then the weakness extends all over the body. The above symptoms are very often found in operatic singers, in play actors, auctioneers--all who use the voice a great deal. Nausea in the throat. Expectoration yellow, green, offensive; after coughing and expectorating the patient feels very hollow and empty.
