Felons and whitlows are very painful, being an inflammation of the covering membrane of the bone, and usually attack the finger joints.
As soon as matter forms, an incision may be made with a lancet to let it out. Dr. Thomson recommends burning a piece of punk the size of a pea on the affected part, covering the other portions of the finger with a cloth or napkin wetted with cold water. The burning may be repeated, if necessary; and the pain, it is said, is very slight. As soon as the vitality of the skin is destroyed, it is to be punctured with a needle, slightly elevated, and a small portion of it cut away, so that the pus may escape. This accomplished, the elm and ginger poultice may be applied as on any other sore.
