De dolore disputatio medica

LI.
Pains draw the vital faculty back to its principle, as Hippocrates and Galen testify in the second commentary on Hippocrates' Prognostics, part 10.

LII.
Pain draws blood to itself and creates a phlegmon an inflammatory lesion or abscess. Galen, De Curanda Ratione per Sanguinis Missionem, chapter 8.

LIII.
It sharpens and irritates inflamed [parts] and provides an occasion for fluxes. Book 1, De Compositione Medicamentorum.

LIV.
Indeed, pain compels the mind to be moved: for under it, heat departs, and [the body] grows cold, stiff, and trembles, and finally dies. For in these cases, the innate heat flees to the principle, and is resolved and extinguished: and it brings about death and fainting, by the testimony of Galen, 2 De Symptomatum Causis, 5.

LV.
Galen left the same thing testified, saying: "From vehement pain, those whose vital strength is infirm die: because the essence of their soul is dissolved." 5 Locis Affectis, 1.

LVI.
Nor is pain always so dangerous that it does not sometimes admit a cure. Wherefore, we must descend to this very [subject].

INDICATIONS.

LVII.
The indications by which the cure is directed are either ordered or unordered.

LVIII.
Ordered are those which the legitimate order of healing prescribes: and this is the order whereby the cause is removed before that which has emanated from it. Galen, book 12, Methodus Medendi, 1. He called one cure "by itself" and the other "by accident."
