-When a limb receives some wound or twist without the breaking of a bone, there may be breaking or stretching of ligaments or muscles. This constitutes a sprain. It is evidenced by pain and swelling, and, it may be, by extravasation of blood causing a bruised appearance. General Treatment.-When a limb or a joint is sprained it should be placed in water as hot as can be borne, in which tincture of arnica (a teaspoonful to the quart) has been mixed. This may be repeated every four hours till the inflammation and pain have subsided. Then if it is a joint, as the ankle joint, it must be strapped with broad strips of adhesive plaster to give it support, and the patient must then walk about; or move and use the joint, if it is not in the lower limb. The joint must on no account be allowed to become stiff, and if movement causes a little pain, that must not be minded.
Medicines.-(Every hour until the pain subsides, then less often.)
-If there is bruising as well as sprain.
-Pain, restlessness, and stiffness.
-Stiffness remaining after a sprain.
