§ 191. Angina pharyngea, pharyngitis.
This inflammation is generally a part of angina faucium. The swelling and redness are invisible except when the inflammation is seated high up. The stylohyoidei, styloglossi, mylohyoidei, hyoglossi, stylo-pharyngei muscles, and the constrictor muscles of the pharynx, are affected; deglutition is very painful, and more or less impeded on account of the dryness of the parts; the food frequently returns by the nose, and deglutition frequently occasions a violent and spasmodic cough. This disease is in many cases a sequel of angina faucium. The inflammation existing in hydrophobia is similar to angina pharyngea.
Besides Aconite, we have the following remedies for this inflammation: Bell., Hyoscyam. and Stram., when deglutition is impeded by spasm; Bell., Merc, and Canthar. when the difficulty of deglutition is occasioned by inflammation. If the patient feel as if the food were passing over a lump, over a rough, sore, burning body, Ignat., Pulsat, Nux v., Mercur., Arsenic and Carbo veg. are indicated. Nux vom. is particularly indicated when the disease is occasioned by an acrid state of the stomach, occasioning the rising of a burning, corroding fluid in the throat, which frequently causes an inflammatory condition of the pharynx.
