On the contrary, when once the fury of the attack has passed its climax, especially if another joint should become involved, the whole picture changes as if by magic. The pain fades away to one-fifth of its former intensity within twenty-four, or even within twelve hours; three-fourths of the swelling follows suit in forty-eight hours; and within three or four days' time the patient is moving the joint with comparative ease and comfort. After he gets up at the end of his six weeks, the knee, though still weak and stiff and sore, within a few weeks' time "limbers up" completely, and usually becomes practically as good as ever. In short, the violence and swiftness of the onset are only matched by the rapidity and completeness of the retreat. It would probably be safe to say that not more than one joint in fifty, attacked by rheumatism, is left in any way permanently the worse. But, alas! to counterbalance this mercifulness in the matter of permanent damage, unlike most other infections, one attack of rheumatic fever, so far from protecting against another, renders both the individual and the joint more liable to other attacks. The historic motto of the British in the War of 1812 might be paraphrased into, "Once rheumatic, always rheumatic." The disease appears to be lost to all sense of decency and reason; and to such unprincipled lengths may it go, that I have actually known one luckless individual who had the unenviable record of seventeen separate and successive attacks of rheumatic fever. As he expressed it, he had "had rheumatism every spring but two for nineteen years past." Yet only one ankle-joint was appreciably the worse for this terrific experience.
