The abiding chronic inflammation indicated by local heat, swelling, and inflammation of the affected tissues may be variously treated. The joints may be thoroughly fomented with tolerably hot water or by means of the local vapor bath for half an hour, morning and night, and then be gently rubbed for ten or fifteen minutes with iodine or weak mercurial ointment or with the compound camphor or acetic turpentine liniment, or, if these are too stimulating, with some bland oil, such as cod-liver or neats' foot or cocoa oil, after which should be applied hot-water compresses or linseed poultices or a wrap of soft cotton wool covered with oiled silk and secured by an elastic, moderately tight roller. If these means prove inefficient and the inflammatory process grow more {101} indolent, counter-irritants may be conjoined with or substituted for them. Small fly blisters or strong iodine paint may be applied close to the joints, or the ordinary iodine tincture may be brushed over them, or the above ointments or liniments and one of the bland oils may be more forcibly rubbed in. The prolonged rubbing of these stiff, swollen joints with oil is not valued as much as it deserves. Compression of the thickened tissues by means of a thick envelope of cotton wool and thin flannel or rubber bandage sometimes acts very well, probably by reducing the amount of blood and interfering with cell-growth or promoting cell-degeneration. Hot sand-baths to the affected joints are sometimes useful. These several measures should be perseveringly applied, and in proportion as chronicity prevails the active and passive movements of the articulations and massage of the muscles and adjacent tissues should be daily and efficiently practised.
