Tongue greatly swollen, often to double its usual size, upper surface white or brownish, smooth or cracked, covered with tough mucus, under surface red, ulcers on sides of tongue; severe pain which is increased by motion, making speaking, chewing, and swallowing difficult or impossible; drooling of saliva; glands of neck enlarged; in severe cases obstruction to circulation in head, and interference with respiration; high fever and full pulse.
This is a very rare disease, seldom occurring except as the result of direct injury to the tongue, as from a bum, a caustic application, or the sting or bite of an insect With the application of proper remedies recovery usually takes place, though in severe cases death may occur from suffocation.
Apply general treatment to subdue the fever, and frequent sitz baths for derivative effect. Apply ice locally, allowing the patient to hold pieces of ice in his mouth. Keep the tongue moistened with soothing lotions, as slippery-elm and flaxseed tea. If ulcers form, use chlorate of potash lotion.
In chronic inflammation of the tongue when deep cracks or fissures are formed, the use of lotions of chlorate of potash and carbolic acid, and the application of a strong solution of nitrate of silver, ten or fifteen grains to two tablespoonfuls of water, constitute the best remedies.
