Fever (a phenomenon subjectively perceived as a)

Fever, a phenomenon subjectively perceived as a sensation of excessive heat, but objectively confirmed by an increase in body temperature. Fever can be general and local: the former occurs with fever on the basis of disruption of thermoregulation in the body, while the latter occurs with inflammation and arterial hyperemia in the peripheral parts of the body. In these cases, fever depends on the influx to the peripheral parts of the body of blood that is more heated from deeper parts of the body, which factor, in the development of the aforementioned disorders of local circulation in deeply located organs, no longer occurs. But in the origin of local fever, an important role is also played by the local increase in metabolism in tissues under the influence of the indicated pathological processes. General fever, however, can sometimes be purely subjective, without an increase in general body temperature, which is observed in neurotics, usually hand-in-hand with vasomotor deviations. To explain the latter phenomenon, it should be borne in mind that a person evaluates the temperature of the environment according to the condition of his skin vessels.
