ARM BATH.
This is simply holding the arm in water of proper temperature. It is extremely useful in such painful affections as felons, sprains, and nearly all injuries of the hand and arm. Ulcers and acute and chronic skin diseases of the hands and arm are usually benefited by this bath. If cold water is painful, its application should be preceded by that of hot water, or alternated with it. Cold hands should be frequently rubbed in cool water, and alternately immersed for a few minutes each in hot and cold water. In case of painful felons, the arm must be immersed to the elbow to relieve the pain, although the disease is only in the finger.
