[Venous pain]

Venous pain is exceptionally little known and is described only vaguely and imprecisely. It can be elaborated as follows: venous pain is a chronic, heteroclitic and composite pain. All venous pain is, by definition, individual and open to considerable subjectivity. Venous deficiency ends up by altering the functioning of other organs which depend on it for their metabolism. The pain which arises will, because of this, be a composite pain. The two principal types of venous deficiency are described, as well as the extremely important role played by the sense receptors which as far as possible equilibrate the circulation as it becomes more and more deficient and inefficient. The nociceptors are not apparent until late on, when the danger of destruction or tissular damage is imminent or has already begun. The author explains in detail, and in three developed stages, the progress of the degradation of the return circulation, the causes, the symptoms, and why pain appears to replace chronic discomfort.
