When the Rheumatism was attended with Inflammation and Swelling of the Joints, we blooded freely, gave cooling Purges, and the saline Draughts with Nitre, along with Plenty of weak diluting Liquors, and prescribed a cool low Diet.
After the Violence of the Fever and Inflammation was abated, fomenting the Parts, and rubbing them with the saponaceous or volatile Liniments, sometimes hastened the Discussion of the Swelling; as did likewise the Application of Blisters[66], after the Inflammation was entirely gone; but it ought to be noticed, that if volatile Liniments or Blisters are used too soon, they will sometimes occasion violent Inflammation and Pain[67].
Rheumatic Cases of this Kind are often very obstinate, and require a considerable Length of Time before they are got the better of; and frequently more or less of the Swelling, especially of the Wrists and Joints of the Fingers, remains ever after; and Patients, who have once had the Rheumatism in this violent Degree, are always subject to Relapses; as are even those who have had the Rheumatism but slightly.
Mercury[68] has been recommended in the Cure of Rheumatisms; but I never found it do any Service by itself, except in Cases complicated with venereal Symptoms; though I have often given it, and even sometimes gone so far as to raise a Salivation, where the Pains were most severe in the Night; and the Patient, at the same Time, thought he had some Reason to suspect a venereal Taint, though no external Symptom appeared. However, many good Practitioners have recommended small Doses of Calomel to be given at Nights, and next Morning a Purge; in which Way, I think, I have observed good Effects from its Use.
The Bark was frequently of Use in restoring the Strength, and removing those rheumatic Pains which remained after Fevers, and other Disorders; but, in other Cases, it had little Effect.
When the Rheumatism continues long, and has taken deep Root, Sydenham[69] advises to bleed from Time to Time, at some Weeks Distance; which, he says, will either entirely remove the Disease, or bring it to that Condition, that the Remains of it will be easily extirpated by an Issue; and giving some of the volatile Salts in Canary Wine, Morning and Evening. I have always observed in rheumatic Cases, which continued long, that, after free Evacuations, the Patients received more Benefit from a mild low Diet, continued for some Time, and the Use of diluting Decoctions with mild Diaphoretics, while they took gentle Purges once or twice a Week, than from any other Remedies.
I have given Half an Ounce of Soap a Day, for a considerable Time, in some old rheumatic Cases, in the Manner recommended by the late Dr. John Clerk of Edinburgh, as mentioned by Dr. Pringle; and, I think, with Advantage; but have not had sufficient Trials to ascertain the Merits of this Medicine.
Dr. Sydenham, in treating of the Rheumatism, which he calls scorbutic, says; that after it had resisted Bleeding, Purging, low Diet, and other Remedies, he has cured it by giving thrice a Day two Drachms of an Electuary made of conserv. cochlear. horten. recent. unc. ij. lujul. unc. i. pulv. ar. comp. drachm vi. cum syrup. aurant. q. s. drinking after it three Ounces of a Water drawn from Brunswick Beer, and some of the antiscorbutic Plants.
There is no Disorder which Soldiers are so apt to counterfeit as the Rheumatism, when ever the Duty in the Field is severe; but while there is no Fever or Size in the Blood, or other evident Marks of the Distemper, and the Men look healthy, there is always Reason to suspect Imposture.
