Sprains

These generally proceed from some external injury, attended with pain, swelling, and inflammation. A fomentation of vinegar, or camphorated spirits of wine, if applied immediately, will generally be sufficient: if not, a few drops of laudanum should be added. The fomentation should be frequently renewed, and the sprained part kept in a state of rest and relaxation.
