De dolore disputatio medica

XXXV.
If it is produced by intemperies: the signs of heaviness and distention are not present: nor is the pain wandering, errant, or unstable: but rather fixed and uniform. Pains are also vehement: because they arise from active qualities.

XXXVI.
If heat infests, heating things have preceded, and cold things help: if cold [infests], the opposites of all these appear.

XXXVII.
If flatus is in the cause: the signs of heaviness are not present: the pain is turgid, wandering, and unstable: tension is perceived: causes generating flatus have preceded: sometimes also, when something erupts from the flatus, the sick perceive relief.

XXXIIX.
If it is a stone or worms, they are also argued by their own signs.

XXXIX.
If a quantity of matter causes affliction, the pain will be heavy or "causing a sense of weight": if it putrefies, it is stinging: if it harms by coldness or heat, it will be evident by its own signs as well.

XL.
Viscous sticky or thick pain is persistent and fixed, the use of things inducing viscosity having preceded.

XLI.
If it rests, the pain will be of almost the same tenor: conversely, if it moves.

XLII.
If it is attracted, the pain or heat of the afflicted part has preceded: if it is transmitted, the signs of coldness, humidity, and also strength in another part are present.

XLIII.
If finally it is generated in the whole, or a part: the signs of a damaged faculty, such as weakening or impeding diseases, or of some extraneous fault, will testify.
