Sec. 179. There is another Kind of Rheumatism, called chronical, or lasting. It is known by the following Characters or Marks. 1. It is commonly unattended with a Fever. 2. It continues a very long Time. 3. It seldom attacks so many Parts at once as the former. 4. Frequently no visible Alteration appears in the affected Part, which is neither more hot, red, or swelled than in its healthy State; though sometimes one or other of these Symptoms is evident. 5. The former, the inflammatory, Rheumatism assaults strong, vigorous, robust Persons: but this rather invades People arrived at a certain Period of Life, or such as are weak and languishing. Sec. 180. The Pain of the chronical Rheumatism, when left to itself, or injudiciously treated, lasts sometimes many Months, and even Years. It is particularly and extremely obstinate, when it is exerted on the Head, the Loins, or on the Hip, and along the Thighs, when it is called the _Sciatica_. There is no Part indeed which this Pain may not invade; sometimes it fixes itself in a small Spot, as in one Corner of the Head; the Angle of the Jaw; the Extremity of a Finger; in one Knee; on one Rib, or on the Breast, where it often excites Pains, which make the Patient apprehensive of a Cancer. It penetrates also to the internal Parts. When it affects the Lungs, a most obstinate Cough is the Consequence; which degenerates at length into very dangerous Disorders of the Breast. In the Stomach and Bowels it excites most violent Pains like a Cholic; and in the Bladder, Symptoms so greatly resembling those of the Stone, that Persons, who are neither deficient in Knowlege nor Experience, have been more than once deceived by them.
