=Treatment.=--At the very outset it may be possible to stop the progress of the felon by keeping the finger constantly wet by means of a bandage continually saturated with equal parts of alcohol and water, at night keeping it moist by covering with a piece of oil silk or rubber. Tincture of iodine painted all over the end of the finger is also useful, and the hand should be carried in a sling by day, and slung above the head to the headboard of the bed by night. If after twenty-four hours the pain increases, it is best to apply hot poultices to the finger, changing them as often as they cool. If the felon has not begun to abate by the end of forty-eight hours, the end of the finger must be cut lengthwise right down to the bone by a surgeon to prevent death of the bone or extension of the inflammation. Poultices are then continued. "Run-around" is treated also by iodine, cold applications, and, if inflammation continues, by hot poulticing and incision with a knife; but poulticing is often sufficient. Attention to the general health by a physician will frequently be of service. =WEEPING SINEW; GANGLION.=--This is a swelling as large as a large bean projecting from the back or front of the wrist with an elastic or hard feeling, and not painful or tender unless pressed on very hard. After certain movements of the hand, as in playing the piano or, for example, in playing tennis, some discomfort may be felt. Weeping sinew sometimes interferes with some of the finer movements of the hand. The swelling is not red or inflamed, but of the natural color of the skin. It does not continue to increase after reaching a moderate size, but usually persists indefinitely, although occasionally disappearing without treatment. The swelling contains a gelatinous substance which is held in a little sac in the sheath of the tendon or sinew, but the inside of the sac does not communicate with the interior of the sheath surrounding the tendon. =Treatment.=--This consists in suddenly exerting great pressure on the swelling with the thumb, or in striking it a sharp blow with a book by which the sac is broken. Its contents escape under the skin, and in most cases become absorbed. If the swelling returns a very slight surgical operation will permanently cure the trouble.
